Publisher's Synopsis
Calista Langley operates an exclusive 'introduction agency' in Victorian London, catering to respectable ladies and gentlemen who find themselves alone in the world. But now, a dangerously obsessed individual has begun sending her trinkets and gifts suitable only for those in deepest mourning - a black mirror, a funeral wreath, a ring set with black jet stone. Each is engraved with her initials. Desperate for help and fearing that the police will be of no assistance, Calista turns to Trent Hastings, a reclusive author of popular crime novels, in order to get to the bottom of this disturbing mystery.
