Kate and Sir Charles gather with a host of memorable guests at the Warwicks' Eaton Lodge for an English country-house weekend. Meet Albert Edward, Prince of Wales; his "darling Daisy," the Countess of Warwick; their friends—and their enemies. Someone has murdered a stableboy and the Prince, smarting over a recent gambling exposé and seeking to avoid scandal, directs Sir Charles to find the killer. But the stakes go up when a guest is shot with the Countess's gun.
