“There are dozens of natural explanations,” he said quickly. “Very likely he’s just gone into the bush to hunt for his dinner.”
Her hand involuntarily went to her breast. “I feel,” she whispered, “as if there were something dreadfully—dreadfully wrong.”
Stonor went outside and lustily holloaed. He received no answer.
It was impossible for them to sit still while they waited. Having seen everything in the house, they walked about outside. Off to the left Imbrie had painstakingly cleared a little garden. Strange it was to see the familiar potato, onion, turnip and cabbage sprouting in orderly rows beside the unexplored river.
Time passed. From a sense of duty they prepared a meal on the shore, and made a pretence of eating it, each for the other’s benefit. Stonor did his best to keep up Clare’s spirits, while at the same time his own mystification was growing. For in circling the shack he could find no fresh track anywhere into the bush. Tracks there were in plenty, where the man had gone for wood, or to hunt perhaps, but all more than twenty-four hours old. To be sure, there was the river, but it was not likely he had still a third canoe: and if he had gone up the river, how could they have missed him? As for going down, no canoe could live in that rapid, Stonor was sure; moreover, he supposed the falls were at the foot of it.
Another thing; both his shot-gun and his rifle were leaning against the fireplace. He might have another gun, but it was not likely. As the hours passed, and the man neither returned nor answered Stonor’s frequent shouts, the policeman began to wonder if an accident could have occurred to him. But he had certainly been alive and well within a half-hour of their arrival, and it seemed too fortuitous a circumstance that anything should have happened just at that juncture. A more probable explanation was that the man had seen them coming, and had reasons of his own for wishing to keep out of the way. After all, Stonor had no precise knowledge of the situation existing between Imbrie and Clare. But if he had hidden himself, where had he hidden himself?
While it was still full day Stonor persuaded Clare and Mary to remain in the shack for a time, while he made a more careful search for Imbrie’s tracks. This time he thoroughly satisfied himself that that day no one had struck into the bush surrounding the shack. He came upon the end of the old carry trail around the falls, and followed it away. But it would have been clear to even a tyro in the bush that no one had used it lately. There remained the beach. It was possible to walk along the stony beach without leaving a visible track. Stonor searched the beach for half a mile in either direction without being able to find a single track in any wet or muddy place, and without discovering any place where one had struck up the bank into the bush. On the down-river side he was halted by a low, sheer wall of rock washed by the current. He made sure that no one had tried to climb around this miniature precipice. From this point the rapids still swept on down out of sight.
He returned to the shack completely baffled, and hoping against hope to find Imbrie returned. But Clare still sat huddled in the chair where he had left her, and looked to him eagerly for news. He could only shake his head.
Finally the sun went down.
“If he is not here by dark,” said Clare with a kind of desperate calmness, “we will know something is the matter. His hat, his ammunition-belt, his hunting-knife are all here. He could not have intended to remain away.”
