Unremarkable legal assistant Gary Thorn goes for a pint with his coworker Brendan, unaware his life is about to change. There, Gary meets a beautiful woman, but she leaves before he catches her name. All he has to remember her by is the title of the book she was reading: The Clementine Complex. And when Brendan goes missing, too, Gary needs to track down the girl he now calls Clementine to get some answers.

And so begins Gary's quest, through the estates and pie shops of South London, to find some answers and hopefully, some love and excitement in this page-turning, witty, and oddly sweet story with a cast of unforgettable characters.
