Detective Kathy Kolla's first case is one for the books. Meredith Winterbottom, a resident of Jerusalem Lane—a quaint section of London inhabited by Eastern European immigrants—and a great-granddaughter of Karl Marx, is found dead. Was she the victim of greedy real-estate developers, or was she killed for the politics of another age? When a second Marx sister is killed, David Brock, Chief Inspector of Scotland Yard, is brought in to help. As Kathy and Brock delve into the Lane's eccentric melting pot, they find unpublished letters from Marx to Engels; a possible fourth volume of Das Kapital; an endless list of shady suspects; and a plot to end Kathy's investigating days for good. Can they unravel the mystery before Kathy's first case is her last?
