Crime fiction: Spenser's last stand, The Nameless Detective and new books by Western Washington authors

William Dietrich, a former Seattle Times reporter and Western Washington University professor, loves to let real events spark his imagination. His compulsively readable "Blood of the Reich" (Harper, 416 pp., $25.99) takes off from a real (and really bizarre) event — a Nazi expedition to Tibet that hoped to discover the Aryan race's origins.
