Tim Ayers, scion of a wealthy Chicago family, has been found dead, floating in Lake Michigan near his luxury boat. Cass reluctantly begins digging only to discover that Tim Ayers was terminally ill. Given the large quantities of alcohol and drugs found in his body, Ayers' death appears to be either an accident or suicide. But there are too many unanswered questions and unexplained coincidences.

But violence is escalating around her, and Cass's persistence has already attracted unwanted attention, uncovering sinister secrets that Cass may end up taking to her grave"-- Book jacket.
