Mystery writer Anne Perry has long mined the Victorian era for material; she's written 36 novels set in mid-Victorian England. Now she's taken a leap forward in time with her novel, "No Graves as Yet," which is based in the years around World War I. Against a backdrop of horrible news from the war, Perry weaves connections between German agents and pacifist students at Cambridge. The book is the first of a series of novels of the World War I era that the Scottish writer is planning. Perry says the book's setting gave her an opportunity to showcase both global and internal conflicts.
