The Jake Cashen Series by Declan James is in the Thriller/Crime Mystery Genre.
Book One: Murder in the Hollows
Only Jake knows and he’s not telling.
One small town’s dark secrets lay hidden in the hollows…
Rumors have swirled around Jake Cashen his whole life. Is he crazy like his father? Is it true they booted him out of the F.B.I. right after he cracked a career-making RICO case? Was he dirty?
He came back to his tiny hometown at the foot of Ohio’s Blackhand Hills to serve as a deputy sheriff. He hopes to punch a clock and keep his head down until retirement.
It was a solid plan. Until someone put a bullet in the head of a revered county judge.
Jake’s new boss knows Jake has a particular set of skills. The Sheriff pins a detective badge on him whether Jake likes it or not. He could have said no. But as Jake watches the locals nearly bungle the case in the first five minutes, he knows he’s all in.
As Jake digs into the murder, he soon learns Judge Rand had enemies in every corner. And someone hiding in plain sight may be plotting to bring his investigation to a deadly end.
To bring a cold-blooded killer to justice, Jake’s forced to confront every truth he’s tried to escape. Even the ones that could bury him.

When Jake learns the victim is his best friend, Ben Wayne, he must push past his crushing grief and process the scene. Two things become horrifyingly clear. Ben was shot through the head with a high-powered rifle, and this was no accident. It was an execution.
As the town grieves, Jake discovers there have been a series of similar killings throughout southern Ohio. The victims were the strongest of men. Hunters. Outdoorsmen. Athletes. Each of them picked off by an unseen killer who lies in wait.
