Indemnity Only: V.I. Warshawski 1 by Sara Paretsky
Meeting an anonymous client on a sizzling summer night is asking for trouble. Especially when the client lies and tells V.I. Warshawski he's the prominent banker John Thayer, looking for his son's missing girlfriend. But V.I. soon discovers the real John Thayer's son - and he's dead.
As V.I. begins to question her mysterious client's motives, she sinks deeper into Chicago's darker side: a world of gangsters, insurance fraud and contract killings. And while she must concentrate on saving the life of someone she has never met, it becomes clear that she is in danger of losing her own.
