Michael Allen Dymmoch

The award-winning first novel pairing gay psychiatrist Jack Caleb with burned-out Chicago cop John Thinnes is a “cunning, adroit debut” (Publishers Weekly).
 
 When a CPA with OCD is found shot dead in his locked apartment with a .38 in his hand, only two people don’t believe he killed himself. One is streetwise and world-weary Chicago homicide detective John Thinnes. The other is the victim’s therapist, Dr. Jack Caleb, whose sudden appearance at the crime scene immediately arouses the cop’s suspicions.
 
 The two men couldn’t be more different. Caleb is wealthy, well-educated, and gay, witty enough to name his housecats Sigmund Freud and B. F. Skinner. Between job burnout and marital trouble, Thinnes lost his sense of humor a long time ago. He’s not sure if the good doctor is an ally or his prime suspect. But as they begin to work together, the unlikely partners discover they do share common ground, most notably as Vietnam vets, and that they might be able to help each other as well as solve a baffling murder . . .
 
 “Winner of [St. Martin’s] Best First Malice Domestic Novel Award . . . this assured and unusual debut boasts expressive language and sinewy notions of suspense.” —Publishers Weekly

The Caleb and Thinnes Mysteries

The Man Who Understood Cats

In this “exciting” sequel to The Man Who Understood Cats, psychiatrist Jack Caleb and cop John Thinnes must solve the murder of a Native American artist (Library Journal).
 
 Native American artist Blue Mountain Cat seems determined to provoke controversy with his new installation, which strikes art patron Jack Caleb as “Andy Warhol meets Jonathan Swift in Indian country.” As the artist’s former therapist, Caleb can’t help wondering what is driving this new aggressively satirical direction with pieces like Red Man’s Revenge and Native American Gothic. There’s something to offend everybody, many of whom are at the opening—including a litigious developer, an outraged Navajo woman, a black-market antiquities dealer, and the artist’s stunning blond wife, who discovers her husband stabbed to death in a gallery room with a bone knife from his own exhibit.
 
 When Chicago homicide detective John Thinnes arrives at the museum, he drafts his friend Caleb to help him navigate the crime scene and the terra incognita of the art world. As the suspects expand to include a desperate museum director, a savage critic, a married mistress, and a shady partner, the shrink and the cop once again find themselves something of an odd couple but a very effective detective duo . . .

The Death of Blue Mountain Cat

With “terse prose,” this “fascinating” entry in the award-winning series pits psychiatrist Jack Caleb and cop John Thinnes against a serial arsonist (Library Journal).
 
 While jogging through Chicago’s Lincoln Park at dawn, Dr. Jack Caleb comes upon a scene of horror—a mob in white robes about to set a police car on fire with the officer inside. Caleb’s training as a medic in the Vietnam War kicks in and he rushes to rescue the man. One cop is saved, but later his female partner is found in another location, stoned to death. Homicide detective John Thinnes has a cop killer on his hands.
 
 But these two attacks are only the beginning in a series of arson fires and murders over the course of a long, hot, deadly summer. Evidence points toward cultists in the Church of Divine Conflagration—but then some of them also fall victim to the pyromaniac. When a physician friend of Caleb is implicated, the psychiatrist works with Thinnes to set a trap for the killer—but it’s one they might not escape unscorched themselves . . .

Incendiary Designs

Psychiatrist Jack Caleb and Chicago cop John Thinnes return in this “well-crafted procedural . . . intriguingly presented . . . spiked by psychological insight” (Booklist).
 
 After a woman is brutally raped in the posh Lincoln Park neighborhood of Chicago and a second rape victim is murdered, the hunt for a serial rapist/killer becomes a “heater” case, front-burnered due to the scrutiny of publicity. The pressure is on Det. John Thinnes and his new partner, a strong-willed feminist cop named Don Franchi.
 
 Psychiatrist Jack Caleb is acting as a police consultant to construct a psychological profile of the rapist, and Thinnes asks his friend to step in and mediate the friction between him and his partner. If they’re going to solve an increasingly complicated and disturbing case that matches the MO of earlier, similar crimes in another Illinois city, they need to find a way to work together . . .

The Feline Friendship

The murder of a Vietnamese woman reawakens wartime trauma for cop John Thinnes and psychiatrist Jack Caleb in an “absolutely gripping” police procedural (Chicago Tribune).
 
 After a woman is shot in the Little Saigon neighborhood of Chicago, Detective John Thinnes realizes he knew the victim when he was stationed in Vietnam. In fact, he was the best man when his friend Bobby Lee married Hue An. When an anonymous tip comes in that Thinnes might be the real father of her son, Tien Lee, who is the prime suspect in her murder, he is pulled off the case and his partner Don Franchi takes over.
 
 At Hue An Lee’s wake, a schizophrenic man insists there is a connection between her death and an unsolved murder in wartime Saigon. Psychiatrist Jack Caleb is called in to help the schizophrenic mourner, but the therapy is kicking up his own PTSD from serving as a medic during the war. Working with Caleb, Thinnes remembers a deadly criminal from his days as an MP in Saigon—known as White Tiger—who he fears has resurfaced in Chicago. Now it’s up to the two vets to stop him . . .
