In The Adventure of The Blackfriar's Bridge, Frank Race, a former attorney turned OSS agent, is drawn into a web of intrigue surrounding a suspicious death in London. The story begins with Race meeting George Gilthorpe, president of the British and Colonial Life Insurance Association, who informs him about a hit-and-run victim found on Lower Thames Street. The deceased, insured by the company, has beneficiaries who are all American partners running a nightclub called the Golden Chest. Gilthorpe expresses concern over the legitimacy of the claim, prompting Race to investigate further.
