The Third Victim — Collin Wilcox

Stalked by a nighttime killer, a woman does whatever it takes to survive
He calls himself Tarot. His first victim was a mother, killed while her daughter slept in the next room. His second was a truck-stop waitress, murdered -- like the first woman -- while she slept. After each one, he sent letters to the newspapers, boasting of his crimes and promising more to come. The third victim will die soon, he tells them. But first, she must be warned.
Joanna is drinking her morning coffee when she finds the switchblade on the floor, dropped through her newspaper slot in the middle of the night. Was it left there by a neighborhood prankster with a dark sense of humor? Or is this the warning of Tarot? Her husband has left her, making Joanna the sole caretaker for their son. Until Tarot is caught, neither of them can count on a good night's sleep.
