Dooley Takes The Fall by Norah McClintock
Dooley's on a mission. A mission to discover what happened the night of classmate Mark Everley's suicide. A suicide that Dooley witnessed and is now under suspicion for due to a previous police record. What makes matters worse? An unfortunate doping at a party that Dooley attends (and shouldn't be attending), causing him to lose all credibility in the eyes of the police and most importantly, his Uncle, who is currently allowing Dooley to reside at his residence. Toss in some romantic interest involving the victim's sister and you have a fast-paced and enjoyable read.
