Willow Foxglove's friend Reg finally spotted some aliens in an outfield. But are the visiting creatures responsible for a murder?

When Reg doesn't turn up for his tour group, Willow is frightened something terrible has happened to him. After an increasingly panicked hunt, she and Harmony find him hiding away from the extraterrestrial life-forms he usually seeks. After Sheriff Wender uncovers a body in the same pasture Reg insists he encountered an alien being, they must consider whether a universal incident has taken place.

As the murder case drags on, unsolved, Willow soon faces increasing pressure on her fledgling business. If the tourists stay away from Aniseed Valley for fear a murderer is on the loose, then she might end up having to close her beloved tea shop.

With Reg's sanity and her business on the line, Willow joins forces with best friend Harmony to uncover the truth, solve the murder, and discover if Aniseed Valley is now a tourist destination for the entire galaxy!
