Chapter 15: The Tapped Wires - Jimmy Dale is watched by The Pretender's spy, and Jimmy has reason to believe the telephone wires are tapped. To allay suspicion Jimmy calls his doctor to make an appointment and slip out un-followed. But the spy had heard words uttered to Jimmy earlier and tells The Pretender. The latter translates them into meaning that certain papers are hidden in an underground office maintained by a crook and instructs his henchman, The Weasel, to get them. Jimmy is also instructed by the Toscin to get the papers. The Grey Seal/Jimmy Dale and the Weasel come together there but neither can find the papers and, following a struggle, the Weasel makes his get-away. Jimmy Dale also leaves before the police arrive. Jimmy Dale gets home safely but The Pretender sends him a threat-message stating that The Grey Seal's next night-time excursion will be his last.
