The Sixth Sense: Book One Special Agent John Flynn is everything Jerry Parker is not: dangerously handsome, coolly charismatic, and respected by his peers. Special Agent Parker is dedicated and meticulous, but his abrasive personality has given him a reputation for being difficult. When new information on a cold case appears, Parker is assigned to work with Flynn, and the sparks fly as their investigative styles clash. Contact with a strange artifact changes everything when it bestows unusual and unpredictable powers on Flynn... and the two men must learn to trust each other before a killer strikes again.
