Psych: Mind-altering Murderebook ISBN 0451232526
Trained to be a detective by his father, blessed with astounding powers of observation and deduction, and cursed with a refusal to take anything seriously, Shawn Spencer has convinced everyone he's psychic. Now, with his best friend, Gus, he's either going to clean up...or be found out.
It's Psych's coolest case ever--the founder of a computer game company has disappeared, and the only way to find him is to search for clues inside the game. But before Shawn can get to level two, he is shocked to discover his partner, Gus, has decided he doesn't want to be a detective anymore and has taken a grown-up job in the real world. Is this the end of Psych? Or is it the end of Gus? Because when a fellow executive at Benson Pharmaceuticals turns up dead, he realizes there's some bad business going on behind closed doors. Now Gus needs Shawn more than ever to solve this puzzle--before he's forced to take an early, and permanent, retirement.
