This is your class if you're a mystery lover. On January 9 we start with Susie Steiner's MISSING, PRESUMED, a British police procedural and fascinating puzzle with an interesting heroine; February 13 we move to Anthony Horowitz' MAGPIE MURDERS, a suspenseful book that is a story within a story, written in the mode of an Agatha Christie mystery; March 20 features Fiona Barton's THE CHILD, a why-dun-it with a story line about a discovered baby's remains; and April 10 we conclude with John Grisham's CAMINO ISLAND, a clever investigation into the burglary of F.Scott Fitzgerald manuscripts from Princeton University.
