Mysterious Mr. Sabin

A late arrival at a fashionable London restaurant turns an ordinary supper into a puzzle. Lord Wolfenden, Densham and the journalist Harcutt are curious about a distinguished older man and his young companion, while Felix, a newly appointed Russian embassy attaché, leaves unexpectedly. E. Phillips Oppenheim opens this mystery novel with small social observations: a reserved table, white roses, an unfamiliar face and the uneasy reactions of those nearby.

The later conversation between Mr. Sabin and Lady Deringham adds another layer to that uncertainty. They recall earlier days in Paris, but he insists on keeping his assumed name and concealing his presence in England, particularly from her son Wolfenden. Their talk blends memories, anxiety about aging and hints of ambitious schemes. Readers interested in intrigue among diplomats and fashionable society can follow a story in which polite conversation carries clues about identity, loyalties and private intentions.
