At the back of the house there was a space of ground where Mrs. Wiles grew a few vegetables for the household's use; it was a clearing made from the heath, but it was not enclosed. Beaumaroy was able to reach the back entrance, by which this patch of ground could be entered from the kitchen. Just by the kitchen door stood that useful thing, a butt for rainwater. It stood some three, or three and a half, feet high; and it was full to the brim almost. With a fresh effort Beaumaroy raised the sack to the level of his breast. Then he lowered it into the water, not dropping it, for fear of a splash, but immersing both his arms above the elbow. Only when he felt the weight off them, as the sack touched bottom, did he release his hold. Then with cautious steps he continued his progress round the house and, coming to the other side, crouched close by the wall again and waited. Where he was now, he could see the fence that separated the front garden from the road, and he was not more than ten or twelve feet from the front door on his left. As he huddled down here, he could not repress a smile of amusement, even of self-congratulation. However he turned to the practical job of squeezing the water out of his sleeves.
In thus congratulating himself, he was premature. His action had been based on a miscalculation. He had heard only Neddy's last exclamation, not the cautious whispers previously exchanged between him and Mike; he thought that the man astride the window-sill himself had kicked something and instinctively exclaimed "What the devil's that?" He thought that the sack was lowered from the window in order to be committed to the temporary guardianship of the Sergeant, who was doubtless looking out for it and, if he had his ears open, would hear its gentle thud. Perhaps the man in the Tower was collecting a second instalment of booty; heavy as the sack was, it did not contain all that he knew to be in Captain Duggle's grave. Be that as it might, the man would climb out of the window soon; and he would fail to find his sack.
What would he do then? He would signal or call to the Sergeant; or, if they had a preconcerted rendezvous, he would betake himself there, expecting to find his accomplice. He would neither get an answer from him nor find him, of course. Equally of course he would look for him. But the last place where he would expect to find him—the last place he would search—would be where the Sergeant in fact was, the house itself. If in his search for Hooper, he found Beaumaroy, it would be man to man, and, now again, Beaumaroy had no objection.
But, in fact, there were two men in the Tower—one of them big Neddy; and the function, which Beaumaroy supposed to have been entrusted to the Sergeant, had never been assigned to him at all; to guard the door and the road had been his only tasks. When they found the bag gone, and the Sergeant too, they might well think that the Sergeant had betrayed them; that he had gone off on his own account, or that he had, at the last moment, under an impulse of fear or a calculation of interest, changed sides and joined the garrison in the house. If he had gone off with the sack, he could not have gone fast or far with it. Failing to overtake him, they would turn back to the cottage; for they knew themselves to be in superior force. Beaumaroy was in greater danger than he knew—and so was Doctor Mary in the house.
Big Neddy let himself down from the window, and put down his hand to lift up the sack; he groped about for it for some seconds, during which time Mike also climbed over the window-sill and dropped on to the ground below. Neddy emitted a low but strenuous oath.
"The sack's gone, Mike!" he added in a whisper.
"Gone? Rot! Can't be! What do you mean, Neddy?"
"I dropped it straight 'ere. It's gone," Neddy persisted. "The Sergeant must 'ave took it."
"No business of his! Where is the fool?" Mike's voice was already uneasy; thieves themselves seldom believe in there being honour among them. "You stay here. I'll go to the door and see if he's there."
He was just about to put this purpose into execution—in which event it was quite likely that Beaumaroy, hearing his approach or his call to the Sergeant, would have sprung out upon him, only to find himself assailed the next instant by another and far more formidable antagonist in the person of big Neddy, and thus in sore peril of his life—when the hum of Captain Alec's engine became audible in the distance. The next moment, the lights of his car became visible to all the men in the little front garden of the cottage.
