At the foot of the ladder a tall man seemed to have sprung out of the ground. He caught the girl in his arms, climbed the ladder, and McGuffog's great hands reached down and seized her and swung her into safety. Up the wall, by means of cracks and tufts, was shinning a small boy.

The stranger coolly faced the pursuers and at the sight of him they checked, those behind stumbling against those in front. He was speaking to them in a foreign tongue, and to Sir Archie's ear the words were like the crack of a lash. The hesitation was only for a moment, for a voice among them cried out, and the whole pack gave tongue shrilly and surged on again. But that instant of check had given the stranger his chance. He was up the ladder, and, gripping the parapet, found rest for his feet in a fissure. Then he bent down, drew up the ladder, handed it to McGuffog and with a mighty heave pulled himself over the top.

He seemed to hope to defend the verandah, but the door at the west end was being assailed by a contingent of the enemy, and he saw that its thin woodwork was yielding.

"Into the House," he cried, as he picked up the ladder and tossed it over the wall on the pack surging below. He was only just in time, for the west door yielded. In two steps he had followed McGuffog through the chink into the passage, and the concussion of the grand piano pushed hard against the verandah door from within coincided with the first battering on the said door from without.

In the garden-room the feeble lamp showed a strange grouping. Saskia had sunk into a chair to get her breath, and seemed too dazed to be aware of her surroundings. Dougal was manfully striving to appear at his ease, but his lip was quivering.

"A near thing that time," he observed. "It was the blame of that man's auld motor-bicycle."

The stranger cast sharp eyes around the place and company.

"An awkward corner, gentlemen," he said. "How many are there of you? Four men and a boy? And you have placed guards at all the entrances?"

"They have bombs," Sir Archie reminded him.

"No doubt. But I do not think they will use them here—or their guns, unless there is no other way. Their purpose is kidnapping, and they hope to do it secretly and slip off without leaving a trace. If they slaughter us, as they easily can, the cry will be out against them, and their vessel will be unpleasantly hunted. Half their purpose is already spoiled, for it is no longer secret.... They may break us by sheer weight, and I fancy the first shooting will be done by us. It's the windows I'm afraid of."
