Mr. Keen - The Mother's Plea Murder Case 

Thank you for sharing another excellent episode of "Mr. Keen." This was one of radio's finest detective shows.

Haven't heard them all (and i understand that hearing them all is a tall task, "Mr.Keen" being one of the most considerably preserved OTR programs) ---but in the dozens of episodes i've heard so far, Mr.K has not traced a single lost person. Lotta dead ones, and he's humiliated folks left and right, the little moralistic bruiser, but he hasn't traced anybody. Just sayin'.
