Barbara Peters, bookstore owner, recently welcomed a long-time friend to The Poisoned Pen. James Byrne is the author of the Hot Book of the Week, Chain Reaction. It’s the third book to feature a wonderful thriller hero, Dez Limerick. Peters and Byrne talk about Dez and the stories that brought him to this most recent one. There are signed copies of Chain Reaction available in the Webstore. https://bit.ly/4giPZIo. But, if you really want to get to know this remarkable lead character, check out the earlier books as well, The Gatekeeper and Deadlock. https://bit.ly/4giPZIo

Here’s the description of Chain Reaction.

Dez Limerick, a man of many skills and a murky past, faces the impossible-a skilled, deadly opponent who anticipates his every move in James Byrne’s Chain Reaction.

Desmond Aloysius Limerick (“Dez” to his friends and close personal enemies) is a man with a shadowy past, certain useful hard-won skills, and, if one digs deep enough, a reputation as a good man to have at your back. He was trained as a “gatekeeper”—he can open any door, keep it open as long as necessary, and control who does—and does not—go through. Now retired from his previous life, Dez still tries to keep his skills up to date.

Knocking around the country, picking up the occasional gig as a guitarist, Dez is contacted by a friend in urgent need of his musical skills. At his behest, Dez flies to the East Coast to a gig at the brand new massive complex, the Liberty Center. But he’s barely landed before he finds himself in the midst of a terrorist attack, a group has taken over the whole center and thousands of hostage lives are in danger. With the semi-willing help of a talented thief, Dez takes on the impossible task of outfighting and outwitting a literal army. But that’s just the beginning, as Dez learns he was actually lured there under false pretenses, by someone who knows more about Dez, his past and his skills than any living person should.

Freelance reviewer Oline Cogdill recently reviewed Alison Gaylin’s We Are Watching. There are signed copies of the book available in The Poisoned Pen’s Webstore. https://bit.ly/4jHWhV4

A mere whisper that something evil is afoot can blow up into nasty rumors spread by conspiracy theorists, as Edgar winner Alison Gaylin explores in the explosive We Are Watching. Gaylin creates an unpredictable plot in which the gullible are convinced to believe outlandish ideas that infiltrate ordinary lives.

Meg Russo and her husband, Justin, are driving their 18-year-old daughter, Lily, to college in Ithaca, N.Y., when skinheads in a pursuing car harass them. It leads to a horrific crash in which Justin is killed. Months later, Meg, who was driving, is still wracked with guilt, and Lily is living at home, withdrawn into her music, wanting to emulate her rock musician grandfather who lives off the grid. Meg and Lily become targets of a cult that believes a fantasy novel Meg wrote back when she was 15 is a harbinger of doom. The bookstore Meg owns in Elizabethville, N.Y., is vandalized and the intimidation escalates, as do Meg’s suspicions that the car crash that took Justin’s life is somehow connected.

Briskly paced, We Are Watching demonstrates how ordinary people can overcome outrageous circumstances. Gaylin superbly shows how close relationships in a small town can be both an asset and a detriment, and how the relationship between a parent and child can undergo changes, with Meg acknowledging she must recover from her own grief to save her family from the violent cultists. In the end, Gaylin  delivers a terrifying story about the most innocuous situation being taken out of context and twisted into a weapon. —Oline H. Cogdill, freelance reviewer

Barbara Peters, owner of The Poisoned Pen, recently welcomed John McMahon back to the bookstore. McMahon said his first appearance at the bookstore was with William Kent Krueger. He appeared then with his book The Good Detective. And, his most recent appearance was just before COVID shut everything down. He talks about his writing, and his new book, Head Cases. There are signed copies of Head Cases available in the Webstore. https://bit.ly/40U9VN9

Here’s the description of Head Cases.

Head Cases follows an enigmatic group of FBI agents as they hunt down a murderer seeking his own justice in this electrifying—and commercial—series debut.

FBI Agent Gardner Camden is an analytical genius with an affinity for puzzles. He also has a blind spot on the human side of investigations, a blindness that sometimes even includes people in his own life, like his beloved seven-year-old daughter Camila. Gardner and his squad of brilliant yet quirky agents make up the Patterns and Recognition (PAR) unit, the FBI’s hidden edge, brought in for cases that no one else can solve.

When DNA links a murder victim to a serial killer long presumed dead, the team springs into action. A second victim establishes a pattern, and the murderer begins leaving a trail of clues and riddles especially for Gardner. And while the PAR team is usually relegated to working cold cases from behind a desk, the investigation puts them on the road and into the public eye, following in the footsteps of a killer.

Along with Gardner, PAR consists of a mathematician, a weapons expert, a computer analyst, and their leader, a career agent. Each of them must use every skill they have to solve the riddle of the killer’s identity. But with the perpetrator somehow learning more and more about the team at PAR, can they protect themselves and their families…before it’s too late?

With an enigmatic case that will keep readers on the edge of their seats and a thoroughly engaging ensemble cast, John McMahon’s Head Cases is a triumph.

The New York Times called John McMahon’s debut novel, The Good Detective “pretty much perfect” and listed it among their “Top Ten Crime Novels of 2019.” The book was a finalist for the 2020 Edgar Award and the ITW Thriller Award, both for Best First Novel. Head Cases is his fourth novel. John currently lives in Southern California with his wife, two kids and a rescue dog. He splits his time between crime writing and his day job in advertising.

This week’s Hot Book of the Week, Johnny Careless, is a debut novel by Kevin Wade, screenwriter and showrunner for “Blue Bloods”. Wade appeared virtually for the bookstore just the other day. There are signed copies of the book available in the Webstore. https://bit.ly/4aC8S82

Here’s the description of Johnny Careless.

“A fast-moving classic crime novel” (John Sandford) crafted by the veteran screenwriter and showrunner for the acclaimed police procedural series Blue Bloods, Johnny Careless is Kevin Wade’s razor-sharp debut novel.

Police Chief Jeep Mullane has been bounced back home to Long Island’s North Shore by a heartbreaking case that both earned him his NYPD detective’s shield and burned him out of the Job. Now heading up a small local police department, he finds himself navigating the same geography he did growing up there as the son of an NYPD cop. Jeep is a “have-not” among the glittering “haves,” a sharp-witted, down-to-earth man in a territory defined and ruled by multigenerational wealth and power and the daunting tribal codes and customs that come with it.

When the corpse of Jeep’s childhood friend Johnny Chambliss—born into privilege and known as “Johnny Careless” for his reckless, golden-boy antics—surfaces in the Bayville waters, past collides with present, and Jeep is pulled into a treacherous web. He is challenged by Johnny’s wealthy and secretive family and his beautiful, enigmatic ex-wife as he untangles a knotted mystery fraught with theft, corrupt local moguls, and decades-old secrets, all while grappling with his own deep-seated grief for his lost pal.

A fast-paced story, Johnny Careless “combines grit and wit in a way that conjures Donald Westlake or Robert Parker in full stride” (Carl Hiassen).

Barbara Peters, owner of The Poisoned Pen, recently welcomed Kemper Donovan to the bookstore. Donovan is a podcaster, host of “All About Agatha”, so it was appropriate that they talked about Agatha Christie before they dove into Donovan’s books. His latest one is Loose Lips. There are signed copies available through the Webstore. https://bit.ly/3PVmqlC

Here’s the description of Loose Lips.

Knives Out meets high seas intrigue on a literary cruise to nowhere in this intelligent, wildly funny locked room mystery for fans of Richard Osman, Anthony Horowitz, Nita Prose, and Agatha Christie!

The USA Today bestselling host of the “All About Agatha” podcast injects the spark and fizz of a Golden Age murder mystery into the present-day, as the ghostwriter’s skills are put to the test aboard a bestselling author’s decidedly insalubrious cruise.

Those who can, do. Those who can’t, teach. So goes the adage, but sometimes, even a first-rate ghostwriter and successful mystery author needs to make a buck. Even if that means setting foot on a cruise ship, something she vowed she’d never do. To top it off, the “Get Lit Cruise” is being organized by Payton Garrett, a very popular, bestselling author—and the ghostwriter’s long-time frenemy from back in their MFA days.

Over the years, Payton has reinvented herself. She gained a wife while ditching her journalist husband—who is also on board. And she’s acquired a rabid following who eagerly snapped up the invitations sent to a select few of her newsletter subscribers. The guests, all female, will receive personalized instruction from experts in five different writing genres, while basking in Payton’s reflected glow.

Between mentoring guests, flirting with Payton’s ex, and taking bets on how long before someone performs a reenactment of Titanic’s “I’m flying!” scene (answer: not long enough), there’s plenty to keep a ghostwriter occupied. But there’s one activity nobody expected: solving a murder.

When an attendee is found dead under suspicious circumstances and several others suffer symptoms of poisoning, there are numerous motives and suspects to choose from. But could it be that the victim wasn’t even the intended target? As the body count rises along with onboard tensions, no one is safe—except, perhaps, for a killer whose scruples have long abandoned ship. And of course, like every well-plotted mystery, this one has an extra twist . . .

James Grippando launched his Jack Swyteck series thirty-one years ago with The Pardon. Now Swyteck is back in the nineteenth book, Grave Danger. Oline Cogdill talks about the latest novel, and you might want to order a copy through the Webstore. https://bit.ly/4gjUaU9

Thank you, Oline, for sharing your review from the South Florida Sun Sentinel.

James Grippando has authored “Grave Danger,” his 19th novel about Jack Swyteck. (Monica Hopkins Photography/Courtesy)

‘Grave Danger: A Jack Swyteck Novel’ by James Grippando. Harper, 329 pages, $30

James Grippando’s propensity for latching on to current events and weaving these issues into brisk, in-depth thrillers are a mainstay of his novels about Miami attorney Jack Swyteck.

“Grave Danger,” Grippando’s 19th novel about Jack, is full of believable twists with attention to details, as he mixes a personal story with an international focus that works well.

Jack’s 9-year marriage to FBI agent Andie Henning is going through a rough patch, brought on mainly because of friction that arises from their individual careers. They truly love each other, and dote on their 8-year-old daughter, Righley. Their therapist suggests they stop their rule about not discussing work, acknowledging how their jobs are often at odds.

Jack agrees to take less controversial cases that would overlap with Andie’s investigations. That lasts about two pages when Jack’s father asks him to represent Avi Zarid, an Iranian woman in a custody battle with her husband, Farid. Avi is accused by Farid of kidnapping their 6-year-old daughter and bringing her to Florida. Avi also is being sued by the Iranian government. Avi supposedly disappeared two years before, escaping from prison after being arrested by Iran’s “morality police” for protesting Iran’s hijab mandate.

The case takes a turn when Avi tells Jack that she is not Avi, but rather Avi’s sister. Zahra. She claims Avi was killed by the Iranian government that is trying to cover up the murder. Jack and Andie become adversaries when the FBI wants her to persuade Jack to drop the case. Jack also receives threats from other sources.

Grippando, who lives in South Florida, steers “Grave Danger” through a swamp of politics, both U.S. and Iranian, that keep the plot churning. There’s Iran’s attitude toward women, the morality police’s power, marriage laws and how politics can affect daily life. Yet these issues do not bog down the plot.

“Grave Danger” maintains a strong emphasis on families that uplifts the plot. Readers will root for Jack and Andie to work out their problems while hoping that Zahra can keep custody so the child is not sent back.

Grippando delivers another timely novel. “Grave Danger” could literally be ripped from the headlines.

Award-winning book critic Oline Cogdill recently reviewed Melissa Larsen’s thriller, The Lost House, which was released just a couple weeks ago. You can order a copy of The Lost House through the Webstore. https://bit.ly/3QaqheJ. Thank you, Oline, for sharing your review from the South Florida Sun Sentinel.

“The Lost House” is filled with strong characters that author Melissa Larsen has carefully sculpted. (Emily Hlavá? Green/Courtesy)

‘The Lost House’ by Melissa Larsen. Minotaur, 352 pages, $28

Questions of identity — who we are, where we came from, what we will be — have long been a fundamental part of mystery fiction. To solve a mystery, the sleuth must discover more about themselves, as does the young woman at the center of the atmospheric “The Lost House.”

Software developer Agnes Glin has had an emotionally remote relationship with her father, Magnus, since she was a child. But she was close to her supportive and loving grandfather, Einar Palsson, who recently died. She has a difficult time believing her sweet grandfather was accused 40 years ago of murdering his young wife and infant daughter in his native Iceland. Although never charged, Einar, a university professor, fled from Bifröst to California with Magnus, then 9 years old, to escape the rampant rumors and being ostracized by his neighbors.

Despite Magnus’ vehement objections, Agnes accepts an invitation from true crime podcaster Nora Carver to travel to Bifröst to discuss the murders on the anniversary. After four decades, Einar remains the prime suspect — the case’s notoriety still fresh to many residents with long memories. Agnes hopes to prove her grandfather innocent, though Nora warns her that might not be the “truth” they uncover.

Agnes’ arrival coincides with the disappearance of another young woman, who is the same age as her grandmother was at the time of the murder.

Larsen infuses “The Lost House” with a vivid look at Iceland so chilling one can almost feel the cold wind. Iceland’s unusual landscape emerges as a character itself. Agnes finds the wide open spaces a bit disconcerting but somehow forges closer relationships: “… so much space here, but there is nowhere to hide,” Agnes says. “Nowhere to go but to each other.”

“The Lost House” is filled with strong characters that Larsen has carefully sculpted, beginning with Agnes. A severe injury forced Agnes to quit her job and move back in with her father. Her “broken life” is comprised of many disappointments, including a breakup with her girlfriend, the loss of her grandfather and the contentious relationship with her father.

More than one character wonder who they would have become if they had lived in a different area. Larsen deftly makes “The Lost House” a succinct story of families, their secrets and the interest in true crime.

Not only can you order a signed copy through the Webstore, https://bit.ly/41Exniz, but there’s also the opportunity to see Davis talk about her latest book at a virtual event hosted by the bookstore. Davis will appear for The Pen on Wednesday, January 29 at 5 PM on the bookstore’s Facebook and YouTube channels.

Here’s the summary of The Stolen Queen.

*A New York Times Bestseller*

From New York Times bestselling author Fiona Davis, an utterly addictive new novel that will transport you from New York City’s most glamorous party to the labyrinth streets of Cairo and back.

Egypt, 1936: When anthropology student Charlotte Cross is offered a coveted spot on an archaeological dig in Egypt’s Valley of the Kings, she leaps at the opportunity. That is until an unbearable tragedy strikes.

New York City, 1978: Nineteen-year-old Annie Jenkins is thrilled when she lands an opportunity to work for former Vogue fashion editor Diana Vreeland, who’s in the midst of organizing the famous Met Gala, hosted at the museum and known across the city as the “party of the year.”

Meanwhile, Charlotte is now leading a quiet life as the associate curator of the Met’s celebrated Department of Egyptian Art. She’s consumed by her research on Hathorkare—a rare female pharaoh dismissed by most other Egyptologists as unimportant.

The night of the gala: One of the Egyptian art collection’s most valuable artifacts goes missing, and there are signs Hathorkare’s legendary curse might be reawakening. Annie and Charlotte team up to search for the missing antiquity, and a desperate hunch leads the unlikely duo to one place Charlotte swore she’d never return: Egypt. But if they have any hope of finding the artifact, Charlotte will need to confront the demons of her past—which may mean leading them both directly into danger.
