Nightlines is a fun medium-boiled private eye novel with an atypical protagonist, Alo Nudger. Nudger has a bad stomach, feels fear (almost all of the time), and he doesn't carry, or even own a gun. The mystery, which is centered on the search for a serial killer, is well-plotted and surprising. The real treat of Nightlines, however, is its focus on the characters, their psychologies, motives, and eccentricities.
