April 8, 1947 "Holy Mackerel" I think we have a case of switched identities. A wealthy eccentric woman who lived in a clutter-filled house, is murdered. Concurrent with the Columbia Pictures films, a Boston Blackie radio series—also starring Chester Morris—aired on NBC June 23 – September 15, 1944, as a summer replacement for Amos 'n' Andy. Lesley Woods played Blackie's girlfriend Mary Wesley; Richard Lane played Inspector Farraday. Harlow Wilcox was the announcer for the 30-minute program.

A new incarnation of the Boston Blackie radio series aired April 11, 1945 – October 25, 1950, starring Richard Kollmar. Maurice Tarplin played Inspector Farraday; Jan Miner was Mary. More than 200 half-hour episodes were transcribed and syndicated by Frederick Ziv to Mutual and other network outlets.
