Critical Mass

Sara Paretsky. Putnam, $26.95 (480p) ISBN 978-0-399-16056-1

V.I. Warshawski helps out her closest friend, Vienna-born Dr. Lotty Herschel, when an unwelcome figure from Lotty’s past resurfaces in MWA Grand Master Paretsky’s stellar 17th novel featuring the Chicago PI (after 2012’s Breakdown). Lotty and another Viennese girl, Kitty Binder, were sent to London in 1939 on the Kindertransport. After the war, Lotty settled in Chicago, while Kitty arrived in the area some years later. Lotty gets in touch with V.I. after Kitty’s drug-addicted daughter, Judy, leaves a message claiming that she and her college-age son, Martin, whom she had left in Kitty’s care, are in danger. Judy then vanishes. V.I.’s investigation takes her from the high-tech world of computer engineering to a literally stinking meth pit in a farm town outside Chicago, on the hunt for the now-missing Judy and Martin. V.I. also unearths WWII secrets related to the race to build an atomic bomb. Paretsky builds the suspense by deftly weaving the contemporary narrative with flashbacks to Lotty’s Austrian childhood.
