Puzzles and Plans

Chief Fleck had spent a sleepless night trying to put two and two together. Instead of the answer being "four" as it should have been each time he completed his figuring the result was "zero." Time and again he mustered the facts into columns, only to succeed in puzzling himself the more.

Two German spies, the Hoffs, had set out together in their motor on their usual mysterious Wednesday mission. Two other persons, two of his most intelligent operatives, Thomas Dean and Jane Strong, had set out on a motorcycle to shadow them.

What had happened?

Otto Hoff had returned to his apartment on foot, hours before his usual time, seemingly much perturbed about something.

Frederic Hoff had arrived back at the apartment, also on foot, some hours later than usual, and the motor had not been returned to its usual garage. Frederic Hoff had appeared to be unusually elated about something.

Thomas Dean was in a doctor's home somewhere up the Hudson with a broken arm and a bad scalp wound and was unable to tell what had become of either Miss Strong or the motorcycle.

Jane Strong had arrived home in a taxicab half an hour before Frederick Hoff, apparently unhurt but in a most peculiar condition of mind. When Chief Fleck had called her on the 'phone she had refused to answer any questions. The best he could get out of her was a promise that she would come to his office in the morning.
