“My study and workroom,” explained Colonel Wragge, with a delightful touch of innocent pride, as though he were a very serious scholar. He placed arm-chairs for us round the fire. “Here,” he added significantly, “we shall be safe from interruption and can talk securely.”

During dinner the manner of the doctor had been all that was natural and spontaneous, though it was impossible for me, knowing him as I did, not to be aware that he was subconsciously very keenly alert and already receiving upon the ultra-sensitive surface of his mind various and vivid impressions; and there was now something in the gravity of his face, as well as in the significant tone of Colonel Wragge’s speech, and something, too, in the fact that we three were shut away in this private chamber about to listen to things probably strange, and certainly mysterious—something in all this that touched my imagination sharply and sent an undeniable thrill along my nerves. Taking the chair indicated by my host, I lit my cigar and waited for the opening of the attack, fully conscious that we were now too far gone in the adventure to admit of withdrawal, and wondering a little anxiously where it was going to lead.

What I expected precisely, it is hard to say. Nothing definite, perhaps. Only the sudden change was dramatic. A few hours before the prosaic atmosphere of Piccadilly was about me, and now I was sitting in a secret chamber of this remote old building waiting to hear an account of things that held possibly the genuine heart of terror. I thought of the dreary moors and hills outside, and the dark pine copses soughing in the wind of night; I remembered my companion’s singular words up in my bedroom before dinner; and then I turned and noted carefully the stern countenance of the Colonel as he faced us and lit his big black cigar before speaking.

The threshold of an adventure, I reflected as I waited for the first words, is always the most thrilling moment—until the climax comes.

But Colonel Wragge hesitated—mentally—a long time before he began. He talked briefly of our journey, the weather, the country, and other comparatively trivial topics, while he sought about in his mind for an appropriate entry into the subject that was uppermost in the thoughts of all of us. The fact was he found it a difficult matter to speak of at all, and it was Dr. Silence who finally showed him the way over the hedge.

“Mr Hubbard will take a few notes when you are ready—you won’t object,” he suggested; “I can give my undivided attention in this way.”

“By all means,” turning to reach some of the loose sheets on the writing table, and glancing at me. He still hesitated a little, I thought. “The fact is,” he said apologetically, “I wondered if it was quite fair to trouble you so soon. The daylight might suit you better to hear what I have to tell. Your sleep, I mean, might be less disturbed, perhaps.”

“I appreciate your thoughtfulness,” John Silence replied with his gentle smile, taking command as it were from that moment, “but really we are both quite immune. There is nothing, I think, that could prevent either of us sleeping, except—an outbreak of fire, or some such very physical disturbance.”

Colonel Wragge raised his eyes and looked fixedly at him. This reference to an outbreak of fire I felt sure was made with a purpose. It certainly had the desired effect of removing from our host’s manner the last signs of hesitancy.

“Forgive me,” he said. “Of course, I know nothing of your methods in matters of this kind—so, perhaps, you would like me to begin at once and give you an outline of the situation?”
