Events at a party seem typical, until a gunshot is heard. The prime suspect is Mrs Davis who claims she had nothing to do with it, and is distraught over the killing. In a unique style for radio dramas, in almost a surreal manner, the interrogation questions are presented.
Police review the details of the clues, and Mrs Davis is taken to trial. The case against her is a good one, but how will the jury decide? Listen in to learn, but whether she is found guilty, or innocent, it remains that a little 22 calibre pistol is now held in the Black Museum as the murder weapon.
