At night time, one ketch-rigged boat is very much like another; but there was something in the angle of her bowsprit, in the rake of her two masts, as well as in the clumsy lines of her hull which made him almost certain that she was the Thor—the same Dutchman in which Max Hilliger had sailed for Germany hardly more than a fortnight ago. Furthermore, she was anchored in precisely the same spot as on the earlier occasion, directly opposite Sunnydene, and visible from any one of the many front windows. Her riding-light was hung low on her foremast, and there was a second light abaft her mizzen.
Having no pressing need to get home to his supper, Darby lingered, anxious to make certain of the identity of the ketch. He could get into the town as easily by walking along the beach as going by the cliff path or the main road.
For some minutes he stood by the side of a tall gorse bush. Nothing happened. But at length as he watched, the vessel's stern light went out, then reappeared and continued to go in and out with curious regularity.
A person ignorant of the Morse code might have believed that a message was being flashed; but Darby Catchpole knew that it was only that one of the crew was pacing the deck and passing to and fro in front of the lantern.
While he waited in the silence, however, he heard the unmistakable sound of a boat's keel crunching on the shingle. He turned and glanced back at Sunnydene. Only the roof and towers could be seen over the edge of the cliff; but from a small window in the east gable there came a quick flash of light. Was it a signal?
Darby crept upwards a few feet and watched for a repetition of the flash. How long he waited he did not know; but when he stepped back three or four paces he again saw the light and almost laughed aloud when he discovered that it was no more than a reflection of the moon in the glass. Yet it had seemed to move. He was not sure even now that it was not a signal to the ketch.
Wondering if the casement were swinging loose on its hinges, he mounted to the top of the cliff and crossed the road to get the window between him and the light of the moon. An owl flew silently over the tops of the intervening fir trees. The house seemed indeed to be deserted. The idea that there still were alien enemies living in it was, after all, ridiculous, and it was only a waste of time to hang around the place any longer.
Beyond the long front garden wall was a pathway leading amongst the gorse and bracken to the main road. Darby determined to take this way back to the town.
He turned into the dark shadows of the path; but stopped abruptly, hearing the click of a gate latch. Some one was coming out by the side gate of Sunnydene. Quick footsteps were approaching, rustling in the dry bracken. He drew back and looked out from his ambush to see a cloaked figure dart past him in the clear light of the moon.
"Max!"
