The specimens are coming back. Nobody is signing for them.
A fox jaw turns up in the intake tray of a university museum. Collections technician Mara Bellamy matches its old break and chipped tooth to photographs taken before the stores were emptied four years ago. She can identify the fox. She cannot find a single record of its return.
Thirty-eight lots of specimens went missing in that move. The man in charge of it was Hugh Fenwick, the mentor who taught Mara how to handle a specimen and when to doubt a label. His account leads her to a dealer who is about to close his shop, and to a mounted cat skeleton whose skull she may once have photographed on Hugh's own bench. A buyer is booked to view it. The dealer won't let anyone near it until Mara can say exactly which part of the animal she believes belongs to the university, and prove it.
Proving it will cost her. The afternoon she needs is the afternoon her colleague Jonah has spent months preparing for the museum's students. And every fact she establishes goes into the record of what Hugh did.
A precise, quietly tense university mystery about evidence, loyalty and the price of telling the truth about someone you admire.
