This is a Perry Mason-styled courtroom drama.

A doctor is separated from his wife. He and his mistress visit his former home in what is supposed to be a negotiating session with his wife.

Gunshots ring out and the wife is dead.

The doctor and his lady friend are charged with murder.

At the end of the story, we are told that this is apparently a true story.

Although I am no lawyer, I am sure that the prosecution does not normally call the defendant(s) to the stand to testify when they present their case.

Also it would surely be highly unlikely that the same attorney would represent two people during the same trial that are separately accused of murder.

Oh well, it's radio drama.
