A crack in everything a Susan Callisto mystery

Summary: Politics can be deadly--when there are toxic secrets to hide. Susan Callisto is nearly thirty and taking stock since her boyfriend, Police Lieutenant Michael Benedict, left her without a goodbye. Susan, with her own political consulting firm, is too busy to think about love anyway--except on lonely summer nights. Political novice Charles Renfrow asks Susan to help him run for mayor. But a friend says Renfrow's biotech company is dumping deadly toxic waste, and Susan decides to find out the truth before committing herself. Instead of the truth, she finds a corpse, Renfrow's gorgeous assistant. Soon violence is shadowing Susan and people close to her. When Renfrow himself turns up dead, the investigation brings Michael back into her life. Then Susan rescues a client's young daughter from her abductor, the person she now reckons is the murderer--but she's only half right--and she must confront the real killer.
