An escaped cannibal, a family curse...and Reginald Worcester turning up on the doorstep. Could things get any worse for the Baskerville-Smythe family? As the bodies pile up, only a detective with a rare brain—and Reggie's is so rare it's positively endangered—can even hope to solve the case. But...there is the small matter that most of the guests aren't who they say they are, the main suspect has cloven feet, and a strange mist hangs over great Grimdark Mire. Luckily the young master has Reeves, his automaton valet, and Emmeline, his suffragette fiancee, on hand to assist.
