Introducing the Hennessey Cape Cod Series

Dissonance book cover | Detective Hennessey

“Kaledin’s fast-paced and erudite murder mystery will leave readers clamoring for the sequel.”
CONALL RYAN, author of House of Cards

Thrown out of the Boston Police Department for going rogue once too often, Detective Tim Hennessey washes up on the shores of Cape Cod, rebuilding his life after an unexpected divorce, a battle with the bottle, and the collapse of his career.

Hired as a consultant to the Barnstable County Police Department, Hennessey is brought in to help out Phil Lipman, the BCPD’s only full-time detective. A series of arsons involving regional performing arts buildings remain unsolved. Also unsolved is a bizarre, gruesome death that shocks and terrifies the Cape. The BCPD doesn’t even know whose body it has on its hands.

Despite the past coming back to haunt him, Hennessey pushes the team forward. He pushes his love life forward at the same time too.

As the wheels of justice grind ahead, things go awry and Hennessey’s frustration with the system boils over. Hanging over everything is his decades-long conflict with a nemesis from the Boston underworld, who now torments Hennessey on Cape Cod while continuing to elude him. Despite his grit, intelligence, and perseverance, two questions confront Hennessey: how will he use his new-found knowledge… and might it even destroy him?
