A humorous 1920s mystery with a supernatural twist. Old Crotchet - her manor, her rules. Cross her at your peril. There's little that will rile a woman more than 300 years of age than the arrival of some flighty young upstart intent upon displacing her. It is Twelfth Night by the old reckoning, and festivities are about to commence as something sinister stirs from its protracted dormancy, awakened, it seems, by the arrival of two young guests. The old ways, they find, should not be treated lightly.
