We're going bananas this week with three old time radio mysteries featuring chimps along with clues and crimes. First, Philip Marlowe looks for an English butler who walks on his knuckles in "The Monkey's Uncle" (originally aired on CBS on March 7, 1950). Then, Simon Templar is saddled with a simian sidekick in "The Chiseling Chimpanzee" from The Saint (originally aired on NBC on December 10, 1950). Finally, Frank Sinatra is asked to serve as bodyguard for a chimp TV star - and later has to find the little guy when he's kidnapped in "Companion to a Chimp" from Rocky Fortune (originally aired on December 15, 1953).
