They chatted for a few moments, then started on their tour of inspection. Though Hilliard was once again keenly on the alert, the examination, so far as he could see, left nothing to be desired. They visited every part of the vessel, from the forecastle storerooms to the tunnel of the screw shaft, and from the chart-house to the bottom of the hold, and every question either of the friends asked was replied to fully and without hesitation.

That evening, like the preceding, they passed with the Coburns. The captain and the engineer—a short, thick-set man named Bulla—strolled up with them and remained for dinner, but left shortly afterwards on the plea of matters to attend to on board. The friends stayed on, playing bridge, and it was late when they said good-night and set out to walk back to the launch.

During the intervals of play Hilliard’s mind had been busy with the mystery which he believed existed in connection with the syndicate, and he had decided that to try to satisfy his curiosity he would go down to the wharf that night and see if any interesting operations went on under cover of darkness. The idea of a midnight loading of contraband no longer appealed to his imagination, but vaguely he wished to make sure that no secret activities were in progress.

He was at least certain that none had taken place up to the present—that Mr. Coburn was personally concerned in, at all events. From the moment they had first sighted the ship until they had left the manager’s house at the conclusion of the game of bridge, not five minutes ago, he had been in Mr. Coburn’s company. Next day it was understood they were to meet again, so that if the manager wished to carry out any secret operations they could only be done during the night.

Accordingly when they reached the launch he turned to Merriman.

“You go ahead, old man. I’m going to have a look round before turning in. Don’t wait up for me. Put out the light when you’ve done with it and leave the companion unlatched so that I can follow you in.”

Merriman grunted disapprovingly, but offered no further objection. He clambered on board the launch and disappeared below, while Hilliard, remaining in the collapsible boat, began to row silently up-stream towards the wharf.

The night was dark and still, but warm. The moon had not risen, and the sky was overcast, blotting out even the small light of the stars. There was a faint whisper of air currents among the trees, and the subdued murmur of the moving mass of water was punctuated by tiny splashes and gurgles as little eddies formed round the stem of the boat or wavelets broke against the banks. Hilliard’s eyes had by this time become accustomed to the gloom, and he could dimly distinguish the serrated line of the trees against the sky on either side of him, and later, the banks of the clearing, with the faint, ghostly radiance from the surface of the water.

He pulled on with swift, silent strokes, and presently the dark mass of the Girondin loomed in sight. The ship, longer than the wharf, projected for several feet above and below it. Hilliard turned his boat inshore with the object of passing between the hull and the bank and so reaching the landing steps. But as he rounded the vessel’s stern he saw that her starboard side was lighted up, and he ceased rowing, sitting motionless and silently holding water, till the boat began to drift back into the obscurity down-stream. The wharf was above the level of his head, and he could only see, appearing over its edge, the tops of the piles of pit-props. These, as well as the end of the ship’s navigating bridge and the gangway, were illuminated by, he imagined, a lamp on the side of one of the deckhouses. But everything was very still, and the place seemed deserted.

Hilliard’s intention had been to land on the wharf and, crouching behind the props, await events. But now he doubted if he could reach his hiding place without coming within the radius of the lamp and so exposing himself to the view of anyone who might be on the watch on board. He recollected that the port or river side of the ship was in darkness, and he thought it might therefore be better if he could get directly aboard there from the boat.
