What happens
Ken Thurston, the man called X, investigates the disappearance of a shipment of streptomycin meant for a hospital in Athens. A grieving mother named Mrs. Masters came to the bureau after her son died without receiving the medicine she had paid for, and Ken's inquiry takes him from the Greek mercantile company to a steamer bound for the island of Xenophon. Along the way he meets a doctor at the hospital, a mysterious passenger, and several men with their own interests in the drug. The Man Called X is a radio series, and this episode aired on November 16, 1947, starring Herbert Marshall as Ken Thurston.

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.
