Serpent's tooth

A busy night in a fashionable restaurant. Minutes later, carnage. 13 people dead and dozens wounded. As Lieutenant Decker, in charge of the police on the scene says, it's your worst nightmare. But at least the culprit seems clear - an embittered ex-employee, Harlan Manz, who ambled up to the bar and opened fire, finally turning the gun on himself. But why did Manz do it? Deck finds that things don't quite add up. Then he questions Jeanine Garrison, daughter of millionaire parents killed in the outrage, and find himself slapped with a sexual harassment suit. Now Decker knows she's involved, and after her brother, who shared the inheritance, is found dead he's sure. But he's not allowed near the woman. Meantime, he can feel her slipping through his fingers and getting away, quite literally, with murder.
