A young woman stops at the grocery store after work, but she never makes it home--at least not all the way. She is stabbed to death in front of her building, her groceries strewn across the cold pavement. Upstairs her neighbor and popular ghost story author Gregory Craig lay dead as well, stabbed in his apartment. When Craig's publisher is found murdered just days later, Detective Steve Carella has a deadly mystery on his hands, one unlike any he's ever had before.
