"Calista Langley operates an "introduction" agency in Victorian London, catering to respectable ladies and gentlemen who find themselves alone in the world. A dangerously obsessed individual has begun sending her gifts suitable only for those in deepest mourning, each engraved with her initials. Calista turns to Trent Hastings, a reclusive author of popular crime novels. Believing that Calista may be taking advantage of his lonely sister, who is one of her clients, Trent doesn't trust her. But as Trent and Calista comb through files of rejected clients in hopes of identifying her tormentor, it becomes clear that the danger may be coming from Calista's own past." -- Back cover.
