Show overview
Mr. Keen Tracer of Lost Persons – The Great Detectives of Old Time Radio has been publishing since 2018, and across the 4 years since has built a catalogue of 56 episodes. That works out to roughly 25 hours of audio in total. Releases follow a monthly cadence, with the show now in its 13th season.
Episodes typically run twenty to thirty-five minutes — most land between 32 min and 35 min — and the run-time is fairly consistent across the catalogue. None of the episodes are flagged explicit by the publisher. It is catalogued as a EN-US-language Arts show.
The catalogue appears to be on hiatus or wound down — the most recent episode landed 4 years ago, with no new episodes in over a year. The busiest year was 2018, with 42 episodes published. Published by Adam Graham.
