The Whitmore Clause

A dead man's final act—a radical will amendment redistributing millions—has made everyone in the Whitmore mansion a suspect. Textile magnate Desmond Whitmore lies poisoned in his locked study on Christmas Eve, and detective Margot Lisle must untangle decades of buried grudges, secret debts, and a family fractured long before tonight. But the deeper she digs, the more she realizes the victim's past holds crimes far worse than his murder—and someone in this house has known all along.
