Kit and her best friend go to a Lincolnshire home to look at action figures from the show Vixens From The Void ahead of their inclusion in a toy museum. They meet other fans and toy collectors, and then the toys are stolen. The toys begin to reappear broken, and then actual bodies appear.
This is the second Kit Pelham novel, so it refers to events that took place in the prior book. It really doesn't have much impact on the opening, except that the other characters are glad she’s present, especially when the theft occurs. The other collectors are geeks in their own way, and Kit recognizes that she might be on the spectrum. She's sensitive to sounds and crowds, must eat certain calorie amounts for each meal, and thinks of things around her with movie or series versions, complete with the year. It absolutely works in this context; faced with TV show fans and other geeky references, she really isn't odd at all. Having a controlling girlfriend constantly tracking her movements and demanding loaded conversations, as well as a misogynistic podcaster harassing her, also allows us to sympathize with her.
There are lots of geeky references throughout the book, since this is a story about geeky toy collectors. They all have a secret that they're hiding, and the characters all have quirks. One by one, the dolls are dismembered and are accompanied by rhymes reminiscent of Agatha Christie. There are five dolls and ten rhymes, so once the dolls are done for, then people are next. Kit is put through an emotional wringer as the book progresses. She gathers clues, and there are plenty of red herrings as we go. The conclusion surprised me, and felt very in keeping with the Agatha Christie references. It's a compelling story and kept me riveted.
