Page after page was finished and tossed aside while his friend leaned back in his arm-chair, looking across at him with patient curiosity. At last, with an exclamation of satisfaction, Smith sprang to his feet, gathered his papers up into order, and laid the last one upon Peterson's desk.

"Kindly sign this as a witness," he said.

"A witness? Of what?"

"Of my signature, and of the date. The date is the most important. Why, Peterson, my life might hang upon it."

"My dear Smith, you are talking wildly. Let me beg you to go to bed."

"On the contrary, I never spoke so deliberately in my life. And I will promise to go to bed the moment you have signed it."

"But what is it?"

"It is a statement of all that I have been telling you to-night. I wish you to witness it."

"Certainly," said Peterson, signing his name under that of his companion. "There you are! But what is the idea?"

"You will kindly retain it, and produce it in case I am arrested."

"Arrested? For what?"

"For murder. It is quite on the cards. I wish to be ready for every event. There is only one course open to me, and I am determined to take it."

"For Heaven's sake, don't do anything rash!"

"Believe me, it would be far more rash to adopt any other course. I hope that we won't need to bother you, but it will ease my mind to know that you have this statement of my motives. And now I am ready to take your advice and to go to roost, for I want to be at my best in the morning."

Abercrombie Smith was not an entirely pleasant man to have as an enemy. Slow and easytempered, he was formidable when driven to action. He brought to every purpose in life the same deliberate resoluteness which had distinguished him as a scientific student. He had laid his studies aside for a day, but he intended that the day should not be wasted. Not a word did he say to his host as to his plans, but by nine o'clock he was well on his way to Oxford.

In the High Street he stopped at Clifford's, the gun-maker's, and bought a heavy revolver, with a box of central-fire cartridges. Six of them he slipped into the chambers, and half-cocking the weapon, placed it in the pocket of his coat. He then made his way to Hastie's rooms, where the big oarsman was lounging over his breakfast, with the Sporting Times propped up against the coffeepot.

"Hullo! What's up?" he asked. "Have some coffee?"

"No, thank you. I want you to come with me, Hastie, and do what I ask you."

"Certainly, my boy."

"And bring a heavy stick with you."

"Hullo!" Hastie stared. "Here's a hunting-crop that would fell an ox."

"One other thing. You have a box of amputating knives. Give me the longest of them."

"There you are. You seem to be fairly on the war trail. Anything else?"

"No; that will do." Smith placed the knife inside his coat, and led the way to the quadrangle. "We are neither of us chickens, Hastie," said he. "I think I can do this job alone, but I take you as a precaution. I am going to have a little talk with Bellingham. If I have only him to deal with, I won't, of course, need you.
