“For my part,” said Holmes, “whatever you may choose to say will go no further.”

I nodded to show my agreement.

“That is well! That is well!” said he. “May I offer you a glass of Chianti, Miss Morstan? Or of Tokay? I keep no other wines. Shall I open a flask? No? Well, then, I trust that you have no objection to tobacco-smoke, to the balsamic odour of the Eastern tobacco. I am a little nervous, and I find my hookah an invaluable sedative.”

He applied a taper to the great bowl, and the smoke bubbled merrily through the rose-water. We sat all three in a semicircle, with our heads advanced and our chins upon our hands, while the strange, jerky little fellow, with his high, shining head, puffed uneasily in the centre.

“When I first determined to make this communication to you,” said he, “I might have given you my address; but I feared that you might disregard my request and bring unpleasant people with you. I took the liberty, therefore, of making an appointment in such a way that my man Williams might be able to see you first. I have complete confidence in his discretion, and he had orders, if he were dissatisfied, to proceed no further in the matter. You will excuse these precautions, but I am a man of somewhat retiring, and I might even say refined, tastes, and there is nothing more unaesthetic than a policeman. I have a natural shrinking from all forms of rough materialism. I seldom come in contact with the rough crowd. I live, as you see, with some little atmosphere of elegance around me. I may call myself a patron of the arts. It is my weakness. The landscape is a genuine Corot, and though a connoisseur might perhaps throw a doubt upon that Salvator Rosa, there cannot be the least question about the Bouguereau. I am partial to the modern French school.”

“You will excuse me, Mr. Sholto,” said Miss Morstan, “but I am here at your request to learn something which you desire to tell me. It is very late, and I should desire the interview to be as short as possible.”

“At the best it must take some time,” he answered; “for we shall certainly have to go to Norwood and see Brother Bartholomew. We shall all go and try if we can get the better of Brother Bartholomew. He is very angry with me for taking the course which has seemed right to me. I had quite high words with him last night. You cannot imagine what a terrible fellow he is when he is angry.”

“If we are to go to Norwood, it would perhaps be as well to start at once,” I ventured to remark.

He laughed until his ears were quite red.

“That would hardly do,” he cried. “I don’t know what he would say if I brought you in that sudden way. No, I must prepare you by showing you how we all stand to each other. In the first place, I must tell you that there are several points in the story of which I am myself ignorant. I can only lay the facts before you as far as I know them myself.

“My father was, as you may have guessed, Major John Sholto, once of the Indian Army. He retired some eleven years ago and came to live at Pondicherry Lodge in Upper Norwood. He had prospered in India and brought back with him a considerable sum of money, a large collection of valuable curiosities, and a staff of native servants. With these advantages he bought himself a house, and lived in great luxury. My twin-brother Bartholomew and I were the only children.

“I very well remember the sensation which was caused by the disappearance of Captain Morstan. We read the details in the papers, and knowing that he had been a friend of our father’s we discussed the case freely in his presence. He used to join in our speculations as to what could have happened. Never for an instant did we suspect that he had the whole secret hidden in his own breast, that of all men he alone knew the fate of Arthur Morstan.
