"As a little girl, Jane has no one. Her mother, the powerful head of a Broadway theater company, has no time for her. She does have one friend - a handsome, comforting, funny man named Michael - but only she can see him.
Years later, Jane is in her thirties and just as alone as ever. Then she meets Michael again-as handsome, smart and perfect as she remembers him to be. But not even Michael knows the reason they've really been reunited.
SUNDAYS AT TIFFANY'S is a love story with an irresistible twist, a novel about the child inside all of us-and the boundary-crossing power of love."
Honestly, I'm not sure this is a mystery, but it's James Patterson so I figured some mystery readers would be interested. It sounds intriguing.
