The winter months finally give way to the promise of spring. Likewise, St. Grimald Priory's residents emerge from the shadows of a dreary winter to face the world-or, in this case, Hoary Plimpton-with hope and excitement.

But the living aren't the only ones determined to enjoy the shifting seasons. A new ghost encroaches on the tranquility of the priory grounds, intent on offending the cats and attacking every person who still breathes with prayers and curses. Another haunts the footpaths, seeking out a particular kind of person on whom to lavish his attentions.

And poor Frederick Bisset, being the only medium around, finds himself the center of both hauntings as one ghost curses him for his nature, and the other chases after him for being young, male, and quite agreeable. No one else sees the ghosts this time, and Frederick is forced to resort to drastic measures to rid Hoary Plimpton of two unsavory specters.

Prudence Honeysett has a trick up her own sleeve as well to ensure the preservation of her lovely garden and her nephew's sanity, though it's a trick that has backfired before in the worst possible way. She is determined, however, for no one, living or dead, ever crosses a Bisset.
