Something is amiss at Maus Haus. Not just the mystery of an unsolved "suicide" which hangs over the old mansion, but something ominous in the present-day residence. When Qwilleran moves in to work on his new gastronomical assignment, strange things begin to happen. First it's a scream in the night, then a vanishing houseboy. But when his old girlfriend disappears, something has to be done. Qwilleran, Koko and Yum Yum set out to solve the mystery--and find a murderer.
