Fiction. Mystery. Thriller. MATT AND LIZ MAY HAVE RETIRED FROM THE POLICE, BUT THAT DOESN'T MEAN A QUIET LIFE. An old friend's sister disappears without a trace. There's no sign of foul play, but she'd been acting very peculiarly . . . Meanwhile, Liz's cousin Christie comes to stay. She takes an immediate-and uncharacteristic-dislike to the local bookshop owner, Gina. Why does everyone put up with her awful behavior? HUNTING WILL-O'-THE-WISPS ON THE MARSHES CAN BE A VERY DANGEROUS HOBBY. Christie is convinced that Gina is manipulating everyone around her. Is she onto something dangerous or just pushing her new friends away? No one believes her suspicions until another friend goes missing late at night on the misty Fen marshes. Can Matt and Liz uncover the truth in time to save lives?
