Mary Russell is well used to dark secrets - her own, and those of her famouspartner and husband, Sherlock Holmes. Trust is a thing slowly given, but overthe course of a decade together, the two have forged an indissoluble bond. Butwhat of the other person Mary Russell has opened her heart to, that thirdmember of the Holmes household: Mrs Hudson? Blood on the floor, a token onthe mantelpiece, the smell of gunshot in the air: all point directly at ClaraHudson - or rather, at Clarissa, the woman she was before Baker Street.
Thekey to Russell's sacrifice lies in Mrs Hudson's past, and to uncover the crime, afrantic Sherlock Holmes must put aside his anguish and push deep into hishousekeeper's secrets, to a time before her disguise was assumed, before hercrimes were buried away. There is death here, and murder, and trust betrayed.
