“I had a little talk with old Cunningham afterwards as to the motive of the crime. He was tractable enough, though his son was a perfect demon, ready to blow out his own or anybody else’s brains if he could have got to his revolver. When Cunningham saw that the case against him was so strong he lost all heart and made a clean breast of everything. It seems that William had secretly followed his two masters on the night when they made their raid upon Mr. Acton’s, and having thus got them into his power, proceeded, under threats of exposure, to levy blackmail upon them. Mr. Alec, however, was a dangerous man to play games of that sort with. It was a stroke of positive genius on his part to see in the burglary scare which was convulsing the country side an opportunity of plausibly getting rid of the man whom he feared. William was decoyed up and shot, and had they only got the whole of the note and paid a little more attention to detail in the accessories, it is very possible that suspicion might never have been aroused.”
