Nikiruka has been called on to assist the Watch once again, but not by Chiamaka this time. The Vigilate has been arrested on suspicion of murder, with a clear motive and no alibi. The Watch is short-staffed, so Custos Vendish, keen to clear his vigilate's name, has come in search of the bookseller who helped Chiamaka before. Nikiruka will have to take on this job alone...

This is the third story in the series.
