Keith had to make a rapid decision. At Morar he had an officer and thirty men stationed. That, surely, was enough. He could, if he wished, send back to Arisaig and bring up some more from there; yet should Arisaig and not Morar prove after all the destined spot, and he had denuded Arisaig of watchers, he would be undone. Loch nan Uamh, the original landing-place, was also provided with a quota, but the distance did not admit of bringing any soldiers thence to-night.

He returned to his orderly and mounted his horse. “I shall ride on to Morar. Go back to Arisaig and tell the Captain so; desire him to keep a close watch on the shore, for the Frenchman is lying off the coast again and nearer in than last night.”

The man saluted and rode off along the rough sandy road, and Keith was left alone with the ship, the moonlight and his own excited thoughts. Not that he stayed to contemplate any of these; he pushed on at a smart trot for Morar, turning over the question of a boat, without which no fugitive could, naturally, reach the ship. He had temporarily confiscated every boat on this stretch of coast except such as were genuinely needed for fishing, to which he had granted a permit. Even of the owners of these he was not sure, for they were all MacDonald of Clanranald’s dependents. It would no doubt have been better to have burnt every one of their craft. Yet even then a vessel could easily despatch one of her own, at the risk of being fired on.

Keith took a last look at the burnished and gently moving expanse of which he must now lose sight, for here the track turned sharply to the right to run round the deep little inlet of Morar. But there was no visible speck upon the sea which might be a boat.

And before long he was approaching the shoreward end of the inlet on the rough sandy track of a road, bordered by dense undergrowth, which ran round, a little higher than the level shore, under trees of no great stature. The tide was coming in fast over the dazzling white sands of Morar, snow under the moon, and drowning the little river which tumbled from the wild, deep freshwater loch behind, where Lord Lovat had sought his last refuge. It was so intensely quiet, and the tide was slipping in so noiselessly, that the roar of the double falls was carried very clearly over the water. Reining up, Major Windham listened for some sign of the patrol which should be going its rounds from the quarters on the other side of the bay, across the river; and, to his displeasure, could detect none. This on a night when a French ship was off the coast! The men must be got out at once.

He touched his horse with the spur and then pulled up again. What was that dark shape down there on the sand? A small boat, and so near the incoming tide that in another quarter of an hour or so it would be afloat. No fisherman could have been so careless as to leave it there, unless it were secured in some way. Brimful of suspicion as Keith was to-night, he had jumped off his horse in an instant, and thrown the bridle over a convenient branch. He knew better than to take the animal plunging into the soft, dry sand of the slope; he was almost up to his ankles himself before he was down.

Yes, he was right; the boat was there for no purpose authorised by him. It had only recently been brought there, for it was not made fast to anything. There were oars in it, but no nets or fishing-lines. It needed no more evidence to convince him that the little craft had been placed there in readiness to take off some person or persons to-night to the strange vessel.

The most lively anger seized Major Windham. What was that damned patrol about not to have discovered this? He must certainly gallop round to their quarters without a moment’s delay and turn out the lazy brutes. His pulses leaping, he plunged up the yielding sand to the tree-shadowed road, turned to throw himself into the saddle—and stood staring like a man bewitched. His horse was gone . . . gone as if swallowed up!

“It is not possible!” said Keith to himself. “I have not been down there two minutes!”

But, evidently, it was possible. Black though the shadows were under the trees, he could tell that they held nothing so solid as a horse. He looked up and down the empty white track, streaked and dappled with those hard shadows; he examined the branch. It was not broken, and the beast could certainly not have twitched his bridle off it. Someone had been watching him, then, and human hands had conveyed the animal away—whither?
