‘In the drawer of his writing table, sir.’
‘See if you can find it now.’
In a few moments Parkes returned. Several keys, each attached to its neatly lettered block of wood, were in the drawer, but that of the boathouse door was missing.
‘That will do, thank you, Smith,’ Austin went on, then, when the man had withdrawn, he turned to the butler. He still seemed nervous and upset.
‘It seems pretty clear Sir William has gone out on the river; now what on earth would he do that for? I wish that man would come back from the doctor’s.’
‘He won’t be long, sir. Say ten minutes there and ten back, and five to make inquiries. He should be here in five or six minutes.’
In about that time Innes returned. Sir William had not called at Dr Graham’s.
Austin and Parkes exchanged troubled glances. The same terrible idea which had been in their minds since the discovery of the missing boat was forcing itself to the front.
The River Cranshaw was a broad and sluggish stream at Halford, and for the two miles or so of its course to the point where it passed Luce Manor. But just below Sir William’s grounds there was a curious outcrop of rock, and the waters had cut for themselves a narrow channel down which, when the river was full, they raced at ever increasing speed till they reached the Cranshaw Falls. Here they leaped over a ledge of rock, not very deep—not, in fact, more than four or five feet—but the river bed at the foot, and for some distance downstream, was so full of huge boulders that the waters danced and swirled, and were churned into a mass of foam as great as might have been expected from a fall of five or six times the height. A dangerous place at which there had been more than one accident. On the last occasion, some twenty years earlier, a party of a man and two girls had allowed themselves to drift into the narrow channel, and in spite of their frantic efforts, their boat had been carried over and all were drowned. The bodies, two of them frightfully disfigured, were found in the smooth water below the rapids. As at the present time, there had just been a severe thunderstorm followed by torrential rain over the whole country, the river was in flood, and the fear that a similar fate might have overtaken Sir William was only too reasonable.
For a few moments none of the men spoke. Then Austin, pulling himself together with an effort, said in a low tone, ‘We must go down the river, I’m afraid. Better bring Smith.’
