Doctor, doctor - give me the news. We've got three old time radio mysteries involving physicians - some good, some bad, but all in the middle of crimes that our heroes must solve. First, a doctor drops dead in Danny Clover's office on Broadway is My Beat (originally aired on CBS on August 4, 1949). Next, Charles Russell investigates a doctor who may be criminally negligent in "An Apple a Day Sent the Doctor Away" from Yours Truly, Johnny Dollar (originally aired on CBS on October 15, 1949). Finally, Sgt. Joe Friday's prime suspect has an unshakable alibi from his doctor in "The Big Impossible" from Dragnet (originally aired on NBC on March 15, 1953).
