XIII: The Murder of the Informer explained

Inspector Flamborough reports the murder of Whalley, a potential informant in the bungalow case, found strangled with a tourniquet similar to the one used on the Heatherfield maid.

What happens

Inspector Flamborough reports the murder of Whalley, a potential informant in the bungalow case, found strangled with a tourniquet similar to the one used on the Heatherfield maid. Sir Clinton and Flamborough discuss the implications, the improved technique of the murderer, and the possible involvement of Silverdale or others from the Croft-Thornton Institute. They consider whether the evidence points to a scientific murderer or a deliberate misdirection.
