Blurb on back cover:
When Rush Strawcutter, the husband of a wealthy dog food heiress, is found bludgeoned to death in a horse stall at an exclusive hunt club, Nora Blackbird is as surprised as anyone. Her surprise turns to shock when her sister Emma is discovered nearby, unconscious and badly bruised. Worse still, the evidence points toward a devious blackmail scheme - with Emma as the main suspect. Investigating with the help of friend and foe alike, Nora inadvertently uncovers the scandalous secrets of some of Philadelphia's high and mightiest... and attracts the unwanted attention of the real killer.
