Penniless and with nowhere to go, Daria Donaldson thinks it's a miracle when she receives a letter naming her as heir to a fortune. Until she follows the summons to an isolated mansion and learns that five others have received the same letter. A widowed barrister. A London journalist. A Scottish golfer. A West End actress. And the enthralling Gabriel Drakos, who clearly isn't the gentleman scientist he claims to be.
None of the six strangers recognize their hostess. But the lady of the manor knows them all too well. Well enough to pit them against one another in a race to uncover her true identity and win her fortune. Her puzzles and cat-and-mouse games will drive some to the edge of their sanity and provoke others to violence. One by one, each houseguest will disappear, leaving Daria alone with her mad hostess and a man who she realizes, too late, is conning them all.
