“10th December, 18—

“DEAR LANYON, You are one of my oldest friends; and although we may have differed at times on scientific questions, I cannot remember, at least on my side, any break in our affection. There was never a day when, if you had had said to me, ‘Jekyll, my life, my honour, my reason, depend upon you,’ I would not have sacrificed my left hand to help you. Lanyon, my life, my honour my reason, are all at your mercy; if you fail me to-night I am lost. You might suppose, after this preface, that I am going to ask you for something dishonourable to grant. Judge for yourself.

“I want you to postpone all other engagements for to-night — ay, even if you were summoned to the bedside of an emperor; to take a cab, unless your carriage should be actually at the door; and with this letter in your hand for consultation, to drive straight to my house. Poole, my butler, has his orders; you will find him waiting your arrival with a locksmith. The door of my cabinet is then to be forced: and you are to go in alone; to open the glazed press (letter E) on the left hand, breaking the lock if it be shut; and to draw out, with all its contents as they stand, the fourth drawer from the top or (which is the same thing) the third from the bottom. In my extreme distress of wind, I have a morbid fear of misdirecting you; but even if I am in error, you may know the right drawer by its contents: some powders, a phial and a paper book. This drawer I beg of you to carry back with you to Cavendish Square exactly as it stands.

“That is the first part of the service: now for the second. You should be back, if you set out at once on the receipt of this, long before midnight; but I will leave you that amount of margin, not only in the fear of one of those obstacles that can neither be prevented nor foreseen, but because an hour when your servants are in bed is to be preferred for what will then remain to do. At midnight, then, I have to ask you to be alone in your consulting-room, to admit with your own hand into the house a man who will present himself in my name, and to place in his hands the drawer that you will have brought with you from my cabinet. Then you will have played your part and earned my gratitude completely. Five minutes afterwards, if you insist upon an explanation, you will have understood that these arrangements are of capital importance; and that by the neglect of one of them, fantastic as they must appear, you might have charged your conscience with my death or the shipwreck of my reason.

“Moreau!” said I. “I know that name.”

“The devil you do!” said he. “What an ass I was to mention it to you! I might have thought. Anyhow, it will give you an inkling of our — mysteries. Whiskey?”

“No, thanks; I’m an abstainer.”

“I wish I’d been. But it’s no use locking the door after the steed is stolen. It was that infernal stuff which led to my coming here, — that, and a foggy night. I thought myself in luck at the time, when Moreau offered to get me off. It’s queer — ”

“Montgomery,” said I, suddenly, as the outer door closed, “why has your man pointed ears?”

“Damn!” he said, over his first mouthful of food. He stared at me for a moment, and then repeated, “Pointed ears?”

“Little points to them,” said I, as calmly as possible, with a catch in my breath; “and a fine black fur at the edges?”

He helped himself to whiskey and water with great deliberation. “I was under the impression — that his hair covered his ears.”

“I saw them as he stooped by me to put that coffee you sent to me on the table. And his eyes shine in the dark.”

By this time Montgomery had recovered from the surprise of my question. “I always thought,” he said deliberately, with a certain accentuation of his flavouring of lisp, “that there was something the matter with his ears, from the way he covered them. What were they like?”

I was persuaded from his manner that this ignorance was a pretence. Still, I could hardly tell the man that I thought him a liar. “Pointed,” I said; “rather small and furry, — distinctly furry. But the whole man is one of the strangest beings I ever set eyes on.”

A sharp, hoarse cry of animal pain came from the enclosure behind us. Its depth and volume testified to the puma. I saw Montgomery wince.

“Yes?” he said.

“Where did you pick up the creature?”

“San Francisco. He’s an ugly brute, I admit. Half-witted, you know. Can’t remember where he came from. But I’m used to him, you know. We both are. How does he strike you?”

“He’s unnatural,” I said. “There’s something about him — don’t think me fanciful, but it gives me a nasty little sensation, a tightening of my muscles, when he comes near me. It’s a touch — of the diabolical, in fact.”

Montgomery had stopped eating while I told him this. “Rum!” he said. “I can’t see it.” He resumed his meal. “I had no idea of it,” he said, and masticated. “The crew of the schooner must have felt it the same. Made a dead set at the poor devil. You saw the captain?”

Suddenly the puma howled again, this time more painfully. Montgomery swore under his breath. I had half a mind to attack him about the men on the beach. Then the poor brute within gave vent to a series of short, sharp cries.
