She brought the butt of the rifle and smashed past the paving-stone that prevented the trap from closing. The stone thudded down, and instantly she swung round the heavy bar that kept it in place. She heard him stamping and screaming above; heard, with a shivering horror, the threats that, as she thought, no human tongue could frame; staggering down the steps, she fell. LVI A high official from Scotland Yard had arrived and was interviewing Dick in the library. “I am wholly responsible. I have always known my brother was queer, and about a year ago I was certain that the horrible taint of madness which his poor mother transmitted to him was developing in a way which could only have one end. I begged of him to see a medical man, but he hated doctors. I brought down the best alienists from London in various guises, sometimes as bailiffs, and occasionally as prospective buyers of our property, but in their presence he behaved so rationally that it was impossible that I could get a certificate. “My own position was a very delicate one.

The man whom the villagers feared and whom they call the Black Abbot, is really Harry. I was a very silent Black Abbot,” he smiled faintly, “and I had no other purpose than to keep Harry indoors. I’m going to say I did not always succeed.” “I’m afraid the truth will have to come out now,” said the official, shaking his head. “I wish it had come out last week,” replied Dick bitterly. “Do you think your brother is responsible for the disappearance of Miss Gwyn?”
