Lew Daney, chief suspect in a jewel robbery and an ensuing murder, vanishes leaving no trace. Once he saved Mary Grier from a knife attack by a madman. Mary Grier now works at Clench House in Scotland as secretary to the miserly Mr. Arkwright, and Mr. Arkwright’s nephew and heir is „"Tiger"” Tim Jordan, an ex-Colonial police officer now holidaying in England and seeking work with Scotland Yard. Jordan doesn’t get much of a holiday but he does get the job, after proving his mettle in pursuit of a murderous criminal Lew Daney. „"The Man at the Carlton"” is a fast-paced, with good twists and turns, an unusual criminal story with a lot of scenery-changes and adventures.
