What happens
Britt Reid and his assistant Kato, the Green Hornet and his valet, respond to an anonymous tip about a meeting at the Vanport boathouse, where they find the general manager, Hart, murdered with a knife in his back. A chase through the fog follows as the killer escapes by river. Reporter Mike Axford interviews Van Port, the company head, who has lost the plans for an anti-atomic bomb device. Reid suspects Van Port's account is too precise, and he sets a trap at the boathouse using a phone call to draw the conspirators together. The series is an old-time radio adventure, and the episode is part of its run sponsored by Orange Crush.

Written from the episode itself; it never gives away the ending. Every recording is remastered for the stream: cleaned of rumble, hiss and mains hum (and the old TV whine where we found it), then levelled in two passes to steady broadcast loudness, so one show is never quieter than the next.
