Of course, if he had happened to be that sort of person, here was the opportunity of a lifetime. The immense booty, the empty house, the solitary neighbourhood, away from the main road and from other habitations; the time, the darkness—but, of course, there was the body to be thought of; that was always the difficulty. What to do with the body—— Here he caught the shriek of the up express, rounding the curve in the line that ran past the waste land at the back of the house. The sound started a new train of thought, and, as he followed it out, his eyes fixed themselves on the unconscious and taciturn Brodski, as he sat thoughtfully sipping his whisky. At length, averting his gaze with an effort, he rose suddenly from his chair and turned to look at the clock on the mantelpiece, spreading out his hands before the dying fire. A tumult of strange sensations warned him to leave the house. He shivered slightly, though he was rather hot than chilly, and, turning his head, looked at the door.
“Seems to be a confounded draught,” he said, with another slight shiver; “did I shut the door properly, I wonder?” He strode across the room and, opening the door wide, looked out into the dark garden. A desire, sudden and urgent, had come over him to get out into the open air, to be on the road and have done with this madness that was knocking at the door of his brain.
“I wonder if it is worth while to start yet,” he said, with a yearning glance at the murky, starless sky.
Brodski roused himself and looked round. “Is your clock right?” he asked.
Silas reluctantly admitted that it was.
“How long will it take us to walk to the station?” inquired Brodski.
“Oh, about twenty-five minutes to half-an-hour,” replied Silas, unconsciously exaggerating the distance.
“Well,” said Brodski, “we’ve got more than an hour yet, and it’s more comfortable here than hanging about the station. I don’t see the use of starting before we need.”
“No; of course not,” Silas agreed. A wave of strange emotion, half-regretful, half-triumphant, surged through his brain. For some moments he remained standing on the threshold, looking out dreamily into the night. Then he softly closed the door; and, seemingly without the exercise of his volition, the key turned noiselessly in the lock.
He returned to his chair and tried to open a conversation with the taciturn Brodski, but the words came faltering and disjointed. He felt his face growing hot, his brain full and intense, and there was a faint, high-pitched singing in his ears. He was conscious of watching his guest with a new and fearful interest, and, by sheer force of will, turned away his eyes; only to find them a moment later involuntarily returning to fix the unconscious man with yet more horrible intensity. And ever through his mind walked, like a dreadful procession, the thoughts of what that other man—the man of blood and violence—would do in these circumstances. Detail by detail the hideous synthesis fitted together the parts of the imagined crime, and arranged them in due sequence until they formed a succession of events, rational, connected and coherent.
He rose uneasily from his chair, with his eyes still riveted upon his guest. He could not sit any longer opposite that man with his hidden store of precious gems. The impulse that he recognized with fear and wonder was growing more ungovernable from moment to moment. If he stayed it would presently overpower him, and then—— He shrank with horror from the dreadful thought, but his fingers itched to handle the diamonds. For Silas was, after all, a criminal by nature and habit. He was a beast of prey. His livelihood had never been earned; it had been taken by stealth or, if necessary, by force. His instincts were predacious, and the proximity of unguarded valuables suggested to him, as a logical consequence, their abstraction or seizure. His unwillingness to let these diamonds go away beyond his reach was fast becoming overwhelming.
But he would make one more effort to escape. He would keep out of Brodski’s actual presence until the moment for starting came.
“If you’ll excuse me,” he said, “I will go and put on a thicker pair of boots. After all this dry weather we may get a change, and damp feet are very uncomfortable when you are travelling.”
“Yes; dangerous too,” agreed Brodski.
Silas walked through into the adjoining kitchen, where, by the light of the little lamp that was burning there, he had seen his stout, country boots placed, cleaned and in readiness, and sat down upon a chair to make the change. He did not, of course, intend to wear the country boots, for the diamonds were concealed in those he had on. But he would make the change and then alter his mind; it would all help to pass the time. He took a deep breath. It was a relief, at any rate, to be out of that room. Perhaps if he stayed away, the temptation would pass. Brodski would go on his way—he wished that he was going alone—and the danger would be over—at least—and the opportunity would have gone—the diamonds——
He looked up as he slowly unlaced his boot. From where he sat he could see Brodski sitting by the table with his back towards the kitchen door. He had finished eating, now, and was composedly rolling a cigarette. Silas breathed heavily, and, slipping off his boot, sat for a while motionless, gazing steadily at the other man’s back. Then he unlaced the other boot, still staring abstractedly at his unconscious guest, drew it off, and laid it very quietly on the floor.
Brodski calmly finished rolling his cigarette, licked the paper, put away his pouch, and, having dusted the crumbs of tobacco from his knees, began to search his pockets for a match. Suddenly, yielding to an uncontrollable impulse, Silas stood up and began stealthily to creep along the passage to the sitting-room. Not a sound came from his stockinged feet. Silently as a cat he stole forward, breathing softly with parted lips, until he stood at the threshold of the room. His face flushed duskily, his eyes, wide and staring, glittered in the lamplight, and the racing blood hummed in his ears.
Brodski struck a match—Silas noted that it was a wooden vesta—lighted his cigarette, blew out the match and flung it into the fender. Then he replaced the box in his pocket and commenced to smoke.
Slowly and without a sound Silas crept forward into the room, step by step, with catlike stealthiness, until he stood close behind Brodski’s chair—so close that he had to turn his head that his breath might not stir the hair upon the other man’s head. So, for half-a-minute, he stood motionless, like a symbolical statue of Murder, glaring down with horrible, glittering eyes upon the unconscious diamond merchant, while his quick breath passed without a sound through his open mouth and his fingers writhed slowly like the tentacles of a giant hydra. And then, as noiselessly as ever, he backed away to the door, turned quickly and walked back into the kitchen.
He drew a deep breath. It had been a near thing. Brodski’s life had hung upon a thread. For it had been so easy. Indeed, if he had happened, as he stood behind the man’s chair, to have a weapon—a hammer, for instance, or even a stone——
He glanced round the kitchen and his eyes lighted on a bar that had been left by the workmen who had put up the new greenhouse. It was an odd piece cut off from a square, wrought-iron stanchion, and was about a foot long and perhaps three-quarters of an inch thick. Now, if he had had that in his hand a minute ago——
He picked the bar up, balanced it in his hand and swung it round his head. A formidable weapon this: silent, too. And it fitted the plan that had passed through his brain. Bah! He had better put the thing down.
But he did not. He stepped over to the door and looked again at Brodski, sitting, as before, meditatively smoking, with his back towards the kitchen.
Suddenly a change came over Silas. His face flushed, the veins of his neck stood out and a sullen scowl settled on his face. He drew out his watch, glanced at it earnestly and replaced it. Then he strode swiftly but silently along the passage into the sitting-room.
