Lady Jane Raytham receives a telegram from her absent husband, setting off a sequence of social calls that introduces key figures, including the formidable Princess Anita Bellini and the eccentric Mrs. Gurden. At the heart of the intrigue is Druze, a portly and seemingly obsequious butler whose mysterious past and secret gender identity entwine him with a web of extortion.
Simultaneously, Peter Dawlish emerges from a grueling prison sentence for forgery, carrying a grievance against the system and a burning desire to settle old scores.

The web tightens around the elite as Leslie pieces together the truth behind Druze's death, exposing the darker impulses of seemingly respectable people.
