In Big Trouble — Laura Lippman

First as a reporter and then as a p.i., Tess Monaghan has learned how to survive and thrive on the streets of Baltimore. But a new case will force her to confront her own past, and a man she loved and lost. It starts when she gets a newspaper photograph of her old boyfriend with a tantalizing shard of headline attached: In Big Trouble. The answers lie far from Baltimore, deep in a world of good-time music, old-fashioned ambiiton, and rich people's games. For Tess must find out what happened to a man she thought she knew, to a woman who may have changed him forever, and to the victims of a killer who dances to a different - and deadly - drummer.
