Welcome to the Billy Boyle World War II Mysteries.

Starred Review from Booklist:

"Benn's ability to sustain his terrific premise while adding depth to his characters makes this long-running series a must for those who love WWII crime fiction."


Starred Review from Publishers Weekly: 

Exhilarating...Bolstered by vivid, scintillating descriptions of air strikes and dogfights involving the legendary all-female Soviet air force unit known as the Night Witches, Benn's high-intensity storytelling shines.


A World War II supersleuth, deprived of his usual backup, unravels a tangled web of criminality in Russia . . . Benn's well-crafted series deepens with every installment.
—Kirkus Reviews

James Benn has done it again with Road of Bones. A real page-turner and enormously entertaining!

—Alex Kershaw, New York Times bestselling author of The Bedford Boys.


Hats off to Billy Boyle! Like a fine Irish whiskey, James Benn's series only gets better, and this time there is a most intriguing addition—a regiment of young Soviet female pilots called the Night Witches.
—Susan Elia MacNeal, New York Times bestselling author of the Maggie Hope mysteries


This book had me at Night Witches; James Benn has done it again! Billy Boyle's return in Road of Bones is an absolute triumph. Sharp, resourceful, and daring, Billy is a hero to root for from first page to last. James Benn brings WWII so vividly to life, you'll hear the whistle of shrapnel and wish you had a SPAM sandwich.

—Deanna Raybourn, New York Times bestselling author of the Veronica Speedwell series.


Road of Bones, the 16th Billy Boyle novel, will be released on September 7, 2021. Available for preorder online and at bookstores.


The Red Horse - Billy Boyle #15, 2020.

"What starts in a sanatorium leads to a high-stakes, dangerous race to find a killer and avert a crisis in the fight against Hitler. Chilling echoes of One Flew over the Cuckoo's Nest and The Prisoner reverberate in every twist and turn of Billy Boyle's life-or-death mission to unmask a plot in the thick of WWII."
—Tom Straw, seven-time New York Times bestselling author writing as Richard Castle


"Billy Boyle has been to some awesome places in James R. Benn's adventurous World War II series. The U.S. Army detective was even a player at the liberation of Paris, where things went badly wrong for him. The Red Horse, which speaks to the dark side of heroism, finds Billy recuperating from that traumatic ordeal (along with a slight meth habit) at the Saint Albans Pauper Lunatic Asylum, now a convalescent hospital in the English countryside for members of the military . . . As historical detective series go, this one is extremely well tended by an author who clearly dotes on his hero. As do we."
—Marilyn Stasio, The New York Times Book Review

"Superlative...Benn maintains a high level of tension throughout and...will engage even first-time readers. This fair-play whodunit stands comparison with the best classic mysteries."

-STARRED REVIEW, Publishers Weekly

"A multilayered plot . . . Benn's latest caper has fascinating historical roots and nicely balances action and investigation."
—Kirkus Reviews


"Once again, Benn draws on little-known aspects of WWII to construct a fascinating wartime thriller . . . Benn skillfully adapts those elements into a compelling variation on a locked-room mystery, delivering another detail-rich novel sure to entrance those who relish deep dives into WWII history."


"As is always the case with Benn's books, the painstaking research is evident, the story crackles with life, and the overlay of fictional characters onto very real historical events is seamless. If you are new to the series, welcome; there are 14 more to keep you busy after you finish this one."

When Hell Struck Twelve - 
Join Billy Boyle in his fourteenth outing, in occupied Paris on the eve of Liberation.

"I've read every book in James R. Benn's series, reviewed most of them, loved all of them, and this is the best one yet."
—BookPage, Starred Review

"...Benn's stellar 14th WWII mystery...The author makes the most of the tense and dramatic backdrop to this high-stakes whodunit. Benn has surpassed himself with this installment."

—Publisher's Weekly, Starred Review  

"This consistently strong series has jumped to another level, with this volume clearly the hands-down best so far . . . a grandly suspenseful, old-school war story . . . Benn's portrayal of the gallimaufry of competing Resistance groups, whose bullets, Billy learns, kill you just as dead as the Germans' more powerful weaponry, adds a fascinating dimension to this exciting story of the sometimes-deadly chaos that accompanied the liberation of Paris."
—Booklist, Starred Review

"The action starts on the first page and doesn't slow down."

-Library Journal


"Benn packs this installment with historical detail and writes with authority and punch."

-Kirkus Reviews

"exceptional...Details about ways to deceive the enemy about Allied army strength lend verisimilitude. Benn has never been better at integrating a whodunit plot line with a realistic depiction of life on or near the battlefield."
—Publishers Weekly STARRED REVIEW  

"Once again, Benn has unearthed a fascinating piece of relatively unknown WWII history and built an engaging mystery around it, combining the Ghost Army with a chilling view of the ugly reparations exacted by Resistance fighters on assumed Nazi collaborators. Liberation, Billy is shocked to learn, has its own dark side."


"Benn's plotting and his first-person narrative both acquire more gravitas as they continue to chart the course of World War II. His latest outing is a complex tale that hinges on a particular moment in world history he captures incisively."
—Kirkus Reviews


Publisher's Weekly on The Devouring: "...suspenseful...Benn does his usual excellent job of incorporating historical background into a fast-paced plot, which barely slows down on the way to the satisfactory resolution."

"Benn's 12th World War II mystery keeps the action coming, with a nifty whodunit chaser."
—Kirkus Reviews

"Benn molds an entertaining story out of Billy and his cohorts’ encounters with odious Swiss bankers and a cadre of Gestapo agents stationed in Bern to protect the loot. Great history here." 

"Extensive historical and military contextual detail, copious suspense, plenty of action, and the innate politics of power are distinctive traits of this acclaimed World War II–set series....The theme of Swiss complicity with the Nazis and their profiteering is absorbing and should appeal to historical fiction fans, mystery readers, and military buffs."
—Library Journal

"This is the twelfth installment of the Billy Boyle World War II Mysteries, and these creations just keep getting better and better."
—Suspense Magazine

"A white-knuckle adventure from the start. . . In The Devouring, Benn has created yet another thoroughly entertaining historical mystery page-turner that is filled with bountiful amounts of action and adventure. His ability to bring fresh understanding to an already well written about period of history is refreshing."
—New York Journal of Books

“The Devouring is packed with the action we have come to expect from the Billy Boyle books. The combination of history, action and suspense in the Billy Boyle novels continues to be irresistible – it’s one of the best crime novel series.”
—Connecticut News

“This is the twelfth installment of the Billy Boyle World War II Mysteries, and these creations just keep getting better and better.”
—Suspense Magazine
