Dickson returned to the others with a grave face.

"Where d'you think the new folk are coming from?" he asked.

Heritage answered, "From Auchenlochan, I suppose? Or perhaps down from the hills?"

"You're wrong." And he told of Léon's mistaken confidences to him in the darkness. "They are coming from the sea, just like the old pirates."

"The sea," Heritage repeated in a dazed voice.

"Ay, the sea. Think what that means. If they had been coming by the roads, we could have kept track of them, even if they beat us, and some of these laddies could have stuck to them and followed them up till help came. It can't be such an easy job to carry a young lady against her will along Scotch roads. But the sea's a different matter. If they've got a fast boat they could be out of the Firth and away beyond the law before we could wake up a single policeman. Ay, and even if the Government took it up and warned all the ports and ships at sea, what's to hinder them to find a hidy-hole about Ireland—or Norway? I tell you, it's a far more desperate business than I thought, and it'll no' do to wait on and trust that the Chief Constable will turn up afore the mischief's done."

"The moral," said Heritage, "is that there can be no surrender. We've got to stick it out in this old place at all costs."

"No," said Dickson emphatically. "The moral is that we must shift the ladies. We've got the chance while Dobson and his friends are locked up. Let's get them as far away as we can from the sea. They're far safer tramping the moors, and it's no' likely the new folk will dare to follow us."

"But I cannot go." Saskia, who had been listening intently, shook her head. "I promised to wait here till my friend came. If I leave I shall never find him."

"If you stay you certainly never will, for you'll be away with the ruffians. Take a sensible view, Mem. You'll be no good to your friend or your friend to you if before night you're rocking in a ship."
