on the man’s progress from the high ground on the other side, could even move parallel with him, if he could come up with him, without the man’s being aware that he was being stalked. He looked at the torrent. Time was precious, and a wetting was nothing now. It is one thing to dip oneself in icy water in the cold blood of a high resolution and quite another to plunge into a flood in the heat of a chase. Grant chose a spot where the river was divided into three parts by two large boulders. If he could succeed in negotiating the first one, he could take the second and the bank in a flying leap, and it would not matter very much if he missed the bank as long as his hands caught at it. He would be across. He stepped back a pace or two and measured the distance to the first boulder with his eye. The first was the flatter of the two, and offered a landing-place; the second was pointed, and must be taken on the run. With an inarticulate prayer he launched himself into space, felt his nailed boots slip as they met the stone, recovered himself, felt the stone heeling over to the black pool beneath, leaped again, but knew even as he leaped that the slipping stone had lacked purchase for his spring, met the second stone sideways, and felt his hands on the far bank just in time to prevent himself going in farther than to his waist. Thankful and breathless, he pulled himself out, hastily wrung as much of the water from his heavy tweed trousers as would prevent him from being hampered by its weight, and made for the high ground beyond. Never had the moor appeared so treacherous. Dry tussocks of grass melted under his feet into bog, dead brambles clung with a living tenacity to his wet tweed, hidden branches of birch rose and hit him as he stepped on the nearer end, holes waited for his feet among the heather. It was more like a music-hall turn, he thought ferociously, than a serious attempt to overtake a criminal. Panting, he came to a turn of the river, and flung himself down to reconnoitre. There was his man, about fifty yards above the manse, moving very slowly and cautiously. It occurred to Grant that he, the pursuer, was having the rough time of it, while the pursued kept a pleasant and well-planned course in the open. Well, it wouldn’t be for long. The minute the man turned into that little back gate that they were laughing so serenely over this morning, he, Grant, would be out of the heather and doubling down the cart-track by the river as hard as he could go. He had a small automatic in his pocket and a pair of handcuffs, and this time he would use them—both if necessary. His man wasn’t armed or he wouldn’t have stolen the pepper-pot from the tea-table, but he wasn’t taking risks any longer. No one’s feelings would be considered any more in this case—his own least of all. Let every female from here to Land’s End have hysterics at once—he wouldn’t care.
Grant was still fuming and glowering and promising himself all sorts of fancy retributions when the man passed the gate. I have always wished that I could have seen Grant’s face at that moment—seen the disgruntled anger and resentment of a man who had tried to do things decently, only to have had his decency taken advantage of, change to the sheer unbelieving astonishment of a small boy beholding his first firework. He blinked hard, but the picture remained the same; what he saw was real. The man had passed the gate. He was now at the end of the manse wall, and making for the bridge. What was the fool doing? Yes, Grant thought of him as a fool. He had worked out a perfectly good way of escape for him—to appeal to Miss Dinmont and lie doggo at the manse—and the fool wasn’t taking advantage of it. He was near the bridge now. What was he doing? What was in his head? There was purpose in every movement. It was not an aimless or even a particularly furtive progress. He seemed to be too wrapped up in the thought of the business ahead to pay much attention to his present circumstances, beyond an occasional glance behind him up the river-bed. Not that there would be much good looking for cover so near the village. Even at this deserted hour, when every one was eating his evening meal and no one was abroad until, an hour later, they came to smoke pipes in the dusk at the bridge-end, there was always the chance of a passer-by, and any appearance of deliberate hiding would defeat its own ends. The man climbed on to the road beside the bridge, but went neither north to the right nor left towards the village. He crossed the road and disappeared on to the river-bank again. What could he get there? Was he going to work round to the hotel, which stood on the point where the river joined the sea, and try to steal the Ford? But he had obviously expected Grant to give the alarm. He would never venture up from the shore to the garage after waiting so deliberately to let Grant give warning. The shore?
Shore! Good heavens, he’d got it! The man had gone for a boat. They would be lying on the deserted shore, out of sight of the village. The tide was in—just on the ebb, in fact—and not a soul, child or adult, would be abroad to witness his departure. Grant hurled himself down the hillside, cursing in a reluctant admiration of the man’s ingenuity. Grant knew the west coaster, and he had a shrewd idea how often these boats were used. If you stay in a west-coast village, you find that the scarcest commodity of all is fresh fish. It might be literally days before any one discovered that MacKenzie’s boat was missing, and even then they would decide that some one had borrowed it, and would save up “the rough side of their tongues”—a course which involved no expenditure of energy—for the borrower when he should put it back. Had Lamont sat and thought all that out at the tea at the manse, Grant thought, as his feet touched the cart-track, or was it a Heaven-sent inspiration in the moment of need? If he had planned it, he thought, racing down the road to the bridge that seemed so strangely distant, then he had also planned that murder in the queue. When one came to think of it, even if one’s grandmother was an Italian, one doesn’t carry daggers about on the off-chance of their being useful. The man was a more accomplished villain than he had given him credit for, in spite of his lack of self-control on two occasions.
Long before Grant had reached the cart-track in his first avalanche down the hillside he had decided on his course of action. This morning, when he had emerged from Carninnish House with Drysdale, he had noticed a boathouse just beyond the house itself, and protruding from it, alongside the little jetty that led from its shelter to the sea, was what Grant in retrospect was sure was the stern of a motorboat. If he was right, and Drysdale was at home, and the light held, then Lamont was as good as caught. But there were three if’s in the affair.
By the time he reached the bridge he was very nearly winded. He had come from the other side of the valley, and now down this one in his heavy fishing boots, with his wet tweeds weighing him down. Keen as he was, it required a real effort of will to make him double that last hundred yards up the north road to the gates of Carninnish House. Once there, the worst was over; the house lay only a few yards inside the gate, in the narrow strip between the road and the sea. When Drysdale’s butler beheld a damp and breathless man at the door, he immediately jumped to conclusions.
“It is the master?” he said. “What’s wrong? Is he drowned?”
“Isn’t he here?” said Grant. “Damn! Is that a motorboat? Can I have a loan of it?” He waved a none too accurate hand towards the boathouse, and the butler looked suspiciously at him. None of the servants had been present at Grant’s arrival in the morning.
“No, you cannot, my lad,” said the butler, “and the sooner you get out of this, the better it will be for you. Mr. Drysdale will make you look pretty small when he comes, I can tell you.”
“Is he coming soon? When is he coming?”
“He’ll be here any minute.”
“But any minute’s too late!”
“Get out!” said the butler. “And have one less next time.”
“Look here,” said Grant, gripping him by the arm, “don’t be a fool. I’m as sober as you are. Come down here where you can see the sea.”
Something in his tone arrested the man’s attention, but it was with obvious fear of personal violence that he approached the sea in company with the madman. Out in the middle of the loch was a rowing-boat, being rapidly propelled seawards down the narrow estuary on the ebbing tide.
“Do you see that?” Grant asked. “I want to overtake that boat, and I can’t do it in a rowing-boat.”
“No, you can’t,” said the man. “The tide goes out there like a mill stream.”
“That’s why I must have the motorboat. Who runs the motor? Mr. Drysdale?”
“No; I do usually when he goes out.”
“Come
