When the stagecoach falls--or was it pushed?--into a ravine in 19th-century Wales, only one of the two young women inside survives. And she, poor lamb, is stricken with amnesia and unable to recollect whether she is runaway apprentice Mary Ramsay or Victoria Merridew, newlywed and newly-widowed bride of the Hon. Gervais Marten of the neighboring Castle Marten. The question is of some moment to Lucian, Lord Marten, since his scapegrace brother Gerry's fortune is at stake, and since he is strongly drawn to the mystery girl, and therefore doubly anxious to prove her outside the limits of consanguinity. But surely he wouldn't want to kill her? Someone does, of course. There are dire warnings scratched in the dust (""Leave Wales"") and several near-misses--not to mention innumerable elderly eccentrics, secret passages, and Sal, the all-too-spirited ex-girlfriend of Gerry. A tangled web, which Tattersall knots and unknots much more skillfully than in her last, Chanters' Chase.
