Deadly Halloween. Sam Hunt Novellas, #3

Sam Hunt was a decorated Vietnam Army sniper. He now lived in a quiet suburb outside of Detroit and yet he enters a battle for justice after his neighbor was murdered in what looked like a hit. Sam and his new Police Detective friend, Roland Royce, solved that case and are now tasked to find the killer of children by poisoned candy. Is this the return of the Halloween poisonings and needles of the 80's? Will they track down the killer before Halloween in two days.
Sam does his best to help Royce as a C. I. as he tries to battle his own inner demons caused by PTSD and alcohol. This book is a novella, longer than a short story, but shorter than a novel.
