The Bank Vault Mystery: Three engineers accompanied by the manager visited the vault of the Consolidated Bank. Shortly after they left, a bag containing $180,000 in cash was missing. And so commenced the famous bank vault case in which Maxwell Fenner, the casual, dapper detective, tracked six suspects through a maze of motives and murder to find a criminal genius.
Brokers' End: It was a clever set up. The Treasurer of the great bond concern of F. W. Strong lay across his elaborate mahogany desk with a bullet hole in his forehead. His revolver was at hand, the ejected shell gleamed from the carpet nearby. Motive? The House of Strong after forty years of business "without loss to any investor" had been declared insolvent by the Court and there were rumors of "irregularities" in the books. It was a clever set up, but then commenced the pursuit and detection of the most diabolically ingenious murders in the experience of the dapper, casual, and disconcertingly naive Maxwell Fenner.
