Mona could see the black outline of the Lockjaw headland from where she was stationed. Her heart seemed to stand still. She turned her eyes first to the pier, then to the Lockjaw, and then to the cloud of black sail outside that grew larger every instant.
Look again—the fishing-boat is coming in; she is almost covering the lamp on the pier; she has swept it down; it is gone, and all is blank, palpable darkness. Mona covers her eyes with her hands.
Is Danny ready? Quick, quick, Danny; one minute lost and all is lost! No light yet on the Lockjaw.
Bravo! Mona's heart leaps to her mouth. There is a light on the Lockjaw Head! Thank God and poor dear Danny forever and ever.
And now, the lamp down, the gorse burning, the merchantman drawing nearer and nearer, what must Mona herself do? She had promised to give the sign to the men in the castle the instant the light on the pier was run down. Then they would know that it was not too soon to pounce down on Kisseck and his men, with part of their plot—the least dangerous part, but still a punishable part—carried into effect. But Mona did not light her lantern. She never meant to do it so soon. She must first see some reason to believe that Christian and his companions had taken Danny's warning.
She waited one minute—two, three. No sign yet. Meantime the black cloud of sail in the bay was drawing closer. There were living men aboard of that ship, and they were running on to the rocks. This suspense was agony. Mona felt that she must do something. But what?
If she were to light her lantern now, she might save the merchantman; but then Christian would be pounced upon and taken. If she were not to light her lantern soon, the ship would be gored to pieces on the Castle Isle, and perhaps all hands would be lost. What was Mona to do? The tension was terrible.
She strode up and down the hillside—up and down, up and down.
Three minutes gone—a fourth minute going. Not a sound from the west coast of the castle. Perhaps Christian, Kisseck, and the rest had not landed. She must not let the merchantman be wrecked. Her lantern must be lighted for the crew's sake. Yes; they were men, living men—men with wives who loved them, and children who climbed to their knees. Mona thought of Christian and of Ruby. It was a fierce moment of conflicting passion.
Four minutes at least had gone. Mona had decided to light her lantern, come what would or could. She was in the act of doing so, when she heard footsteps on the cliff behind her. The four strangers had seen the light on the pier go down. They thought it must be time for them to be moving. Either Kinvig and the other four in the castle had taken their men, or they had missed them. In either case their own time for action had gone.
