Manager of a tourist center in a quaint British village, Julia Lanchester finds herself with more ideas than time. Her boss is the Earl Fotheringill himself, but apart from him, she doesn't mix well with the aristocracy. Unfortunately, toxic mold forces her from her cottage and into one of the earl's countless spare rooms at the Hall. She tries to get a handle on her overload of work, while she finds herself arguing with dinner guests, chaffing at the sudden interest the earl's son has in running the estate, and missing her new beau, Michael Sedgwick.

Her life goes from bad to sinister when Julia discovers poisoned sparrowhawks on the expansive estate grounds. And soon after, she finds one of the Hall's visitors murdered—felled by the same poison. While simultaneously both spooked and angry, she still can't keep herself from snooping, and dragging Michael along into her investigation. But will she find the culprit before her own wings are clipped?
