The Demon Of The Lake Murders by J.L. Melton

It's a snowy day in the city of Decreston, New York. After 25 years of service, Detective Derrick Mallow is retiring from the Decreston Law Enforcement Division.

Mallow needs a change; there are too many bad memories in Decreston. No longer wanting to be a detective, he moves to Lake Tisdale, South Carolina, taking a new position as a patrol officer. But not long after Mallow arrives, there are two mysterious murders and a suicide. A small boy claims he saw a demon leaving one of the crime scenes.

Together with his fellow police officers and the Jenkins County Sheriff's Department, Mallow must piece together the clues and find the killer. But is it the culprit really a demon, or something even more sinister?
