cab. The cab passed howling through preposterously narrow lanes. It turned corners on two wheels with less than inches to spare. It rushed roaring upon knots of people who dissolved with incredible agility before its approach, and it plunged into alleys like tunnels, and it emerged into the wider streets of the more modern part of town with pungent Turkish curses hanging upon it like garlands. Coghlan did not notice. Once he was alone, suspicions sprang up luxuriantly. But he could no more justify them than he could accept the situation his visitors had presented. The two had not asked for money or hinted at it. Coghlan didn't have any money, anyhow, for them to be scheming to get. The only man a swindling scheme could be aimed at was Mannard. Mannard had money. He'd made a fortune building dams, docks, railroads and power installations in remote parts of the world. But he was hardly a likely mark for a profitable hoax, even if his name was mentioned in that memorandum so impossibly in Coghlan's handwriting. He was one of the major benefactors of the college in which Coghlan taught. He had at least one other major philanthropy in view right now. He'd be amused. But there was Laurie, of course.

Its chauffeur beamed at Coghlan and happily demanded six times the legal fare for the journey. Coghlan beckoned to the hotel _Commissionaire_. He put twice the legal fare in the man's hand, said, "Pay him and keep the change," and went into the hotel. His action was a form of American efficiency. It saved money and argument. The discussion was already reaching the shouting stage as he entered the hotel's large and impressive lobby. Laurie and her father were waiting for him. Laurie was a good deal better-looking than he tried to believe, so he muttered, "Professor, president, so what?" as he shook hands. It was very difficult to avoid being in love with Laurie, but he worked at it. "I'm late," he told them. "Two of the weirdest characters you ever saw turned up with absolutely the weirdest story you
