From Wikipedia:

Each story started with a phone call from an insurance executive, calling on Johnny to investigate an unusual claim. Each story required Johnny to travel to some distant locale, usually within the United States but sometimes abroad, where he was almost always threatened with personal danger in the course of his investigations. Johnny’s file on each case was usually referenced as a “matter,” as in “The Silver Blue Matter” or “The Forbes Matter.” Later episodes were more fanciful, with titles like “The Wayward Trout Matter” and “The Price of Fame Matter” (the latter featuring a rare guest-star appearance: Vincent Price).
Johnny usually stuck to business, but would engage in romantic dalliances with women he encountered in his travels; later episodes gave Johnny a steady girlfriend, Betty Lewis. Johnny’s precious recreational time was usually spent fishing, and it was not uncommon for Johnny’s clients to exploit this favorite pastime in convincing him to take on a job.
Each story was recounted in flashback, as Johnny listed each line item from his expense account. The episodes generally finished with Johnny tallying up his account and traveling back to Hartford, Connecticut, where he was based. Most of the expense account related to transportation, lodging, and meals, but no incidental expense was too small for Johnny to itemize, as in “Item nine, 10 cents. Aspirin. I needed them.” The monetary amounts weren’t always literal: the smallest line item Johnny ever recorded was “two cents: what I felt like” after a professional setback; the largest was “one million dollars” (the way he felt after finding a missing woman and her daughter in a snowbound cabin). Each episode would end with Johnny submitting his grand total of miscellaneous expenses. Sometimes Johnny would add a sardonic postscript under “Remarks,” detailing the aftermath of the case. (One case that especially disgusted Johnny ended abruptly with “Remarks — nil!”)

This was recorded on April 1949, meaning that Johnny was played by Charles Russell.

A mysterious horse riding killer stalks the city’s police officers. Good listening.
