They were now close to the beach, and they allowed themselves to drift on until the dark ma.s.s of the wharf loomed up ahead. Then Hilliard dipped his oars and brought the boat silently alongside.

As they had imagined from their distant view of it, the wharf was identically similar in construction to that on the River Lesque. Here also were the two lines of piles like the letter V, one, in front vertical, the other raking to support the earthwork behind. Here in the same relative position were the steps, and to these Hilliard made fast the painter with a slip hitch that could be quickly released. Then with the utmost caution both men stepped ash.o.r.e, and slowly mounting the steps, peeped out over the deck of the wharf.

As far as they could make out in the gloom, the arrangement here also was similar to that in France. Lines of narrow gauge tramway, running parallel from the hut towards the water, were connected along the front of the wharf by a cross road and turn-tables. Between the lines were stacks of pit-props, and Decauville trucks stood here and there. But these details they saw afterwards. What first attracted their attention was that lights shone in the third and fourth windows from the left hand end of the shed. The manager evidently was still about.

"We'll go back to the boat and wait," Hilliard whispered, and they crept down the steps.

At intervals of half an hour one or other climbed up and had a look at the windows. On the first two occasions the light was unchanged, on the third it had moved to the first and second windows, and on the fourth it had gone, apparently indicating that the manager had moved from his sitting-room to his bedroom and retired.

"We had better wait at least an hour more," Hilliard whispered again.

Time pa.s.sed slowly in the darkness under the wharf, and in a silence broken only by the gentle lapping of the water among the piles. The boat lay almost steady, except when a movement of one of its occupants made it heel slightly over and started a series of tiny ripples. It was not cold, and had the men not been so full of their adventure they could have slept. At intervals Hilliard consulted his luminous-dialed watch, but it was not until the hands pointed to the half-hour after one that they made a move. Then once more they softly ascended to the wharf above.

The sides of the structure were protected by railings which ran back to the gables of the tin house, the latter stretching entirely across the base of the pier. Over the s.p.a.ce thus enclosed the two friends pa.s.sed, but it speedily became apparent that here nothing of interest was to be found. Beyond the stacks of props and wagons there was literally nothing except a rusty steam winch, a large water b.u.t.t into which was led the down spout from the roof, a tank raised on a stand and fitted with a flexible pipe, evidently for supplying crude oil for the ship's engines, and a number of empty barrels in which the oil had been delivered. With their torch carefully screened by the black cloth the friends examined these objects, particularly the oil tank which, forming as it did a bridge between ship and sh.o.r.e, naturally came in for its share of suspicion. But, they were soon satisfied that neither it nor any of the other objects were connected with their quest, and retreating to the edge of the wharf, they held a whispered consultation.

Hilliard was for attempting to open one of the doors in the shed at the end away from the manager's room, but Merriman, obsessed with the idea of seeing the unloading of the Girondin, urged that the contents of the shed were secondary, and that their efforts should be confined to discovering a hiding place from which the necessary observations could be made.

"If there was any way of getting inside one of these stacks of props,"

he said, "we could keep a perfect watch. I could get in now, for example; you relieve me tomorrow night; I relieve you the next night, and so on. Nothing could be unloaded that we wouldn't see. But," he added regretfully, "I doubt even if we could get inside that we should be hidden. Besides, they might take a notion to load the props up."

"Afraid that is hardly the scheme," Hilliard answered, then went on excitedly: "But, there's that barrel! Perhaps we could get into that."

"The barrel! That's the ticket." Merriman was excited in his turn. "That is, if it has a lid."

They retraced their steps. With the tank they did not trouble; it was a galvanized iron box with the lid riveted on, and moreover was full of oil; but the barrel looked feasible.

It was an exceptionally large cask or b.u.t.t, with a lid which projected over its upper rim and which entirely protected the interior from view.

It was placed in the corner beside the right hand gable of the shed, that is, the opposite end of the manager's rooms, and the wooden down spout from the roof pa.s.sed in through a slot cut in the edge of the lid.

A more ideal position for an observation post could hardly have been selected.

"Try to lift the lid," whispered Hilliard.

They found it was merely laid on the rim, cleats nailed on below preventing it from slipping off. They raised it easily and Hilliard flashed in a beam from his electric torch. The cask was empty, evidently a result of the long drought.

"That'll do," Merriman breathed. "That's all we want to see. Come away."

They lowered the cover and stood for a moment. Hilliard still wanted to try the doors of the shed, but Merriman would not hear of it.

"Come away," he whispered again. "We've done well. Why spoil it?"

They returned to the boat and there argued it out. Merriman's proposal was to try to find out when the Girondin was expected, then come the night before, bore a few eyeholes in the cask, and let one of them, properly supplied with provisions, get inside and a.s.sume watch. The other one would row away, rest and sleep during the day, and return on the following night, when they would exchange roles, and so on until the Girondin left. In this way, he a.s.serted, they must infallibly discover the truth, at least about the smuggling.

"Do you think we could stand twenty-four hours in that barrel?" Hilliard questioned.

"Of course we could stand it. We've got to. Come on, Hilliard, it's the only way."

It did not require much persuasion to get Hilliard to fall in with the proposal, and they untied their painter and pulled silently away from the wharf. The tide had turned, and soon they relaxed their efforts and let the boat drift gently downstream. The first faint light appeared in the eastern sky as they floated past Ha.s.sle, and for an hour afterwards they lay in the bottom of the boat, smoking peacefully and entranced by the gorgeous pageant of the coming day.

Not wishing to reach Hull too early, they rowed insh.o.r.e and, landing in a little bay, lay down in the lush gra.s.s and slept for three or four hours. Then re-embarking, they pulled and drifted on until, between seven and eight o'clock, they reached the wharf at which they had hired their boat. An hour later they were back at their hotel, recuperating from the fatigues of the night with the help of cold baths and a substantial breakfast.

CHAPTER 8. THE UNLOADING OF THE "GIRONDIN"

After breakfast Hilliard disappeared. He went out ostensibly to post a letter, but it was not until nearly three o'clock that he turned up again.

"Sorry, old man," he greeted Merriman, "but when I was going to the post office this morning an idea struck me, and it took me longer to follow up than I antic.i.p.ated. I'll tell you. I suppose you realize that life in that barrel won't be very happy for the victim?"

"It'll be d.a.m.nable," Merriman agreed succinctly, "but we needn't worry about that; we're in for it."

"Oh, quite," Hilliard returned. "But just for that reason we don't want more of it than is necessary. We could easily bury ourselves twenty-four hours too soon."

"Meaning?"

"Meaning that we mustn't go back to the wharf until the night before the Girondin arrives."

"Don't see how we can be sure of that."

"Nor did I till I posted my letter. Then I got my idea. It seemed worth following up, so I went round the shipping offices until I found a file of Lloyd's List. As you know it's a daily paper which gives the arrivals and departures of all ships at the world's ports. My notion was that if we could make a list of the Girondin's Ferriby arrivals and departures, say, during the last three months, and if we found she ran her trip regularly, we could forecast when she would be next due. Follow me?"

"Rather."

"I had no trouble getting out my list, but I found it a bit disappointing. The trip took either ten, eleven, or twelve days, and for a long time I couldn't discover the ruling factor. Then I found it was Sunday. If you omit each Sunday the Girondin is in port, the round trip always takes the even ten days. I had the Lesque arrival and departure for that one trip when we were there, so I was able to make out the complete cycle. She takes two days in the Lesque to load, three to run to Hull, two at Ferriby to discharge, and three to return to France.

Working from that and her last call here, she should be due back early on Friday morning."

"Good!" Merriman exclaimed. "Jolly good! And today is Thursday. We've just time to get ready."

They went out and bought a one-inch auger and a three-sixteenths bradawl, a thick footstool and a satchel. This latter they packed with a loaf, some cheese, a packet of figs, a few bottles of soda water and a flask of whisky. These, with their caps, rubber shoes, electric torches and the black cloth, they carried to their boat; then returning to the hotel, they spent the time resting there until eleven o'clock. Solemnly they drew lots for the first watch, recognizing that the matter was by no means a joke, as, if unloading were carried on by night, relief might be impossible during the ship's stay. But Merriman, to whom the fates were propitious, had no fear of his ability to hold out even for this period.

By eleven-thirty they were again sculling up the river. The weather was as perfect as that of the night before, except that on this occasion a faint westerly breeze had covered the surface of the water with myriads of tiny wavelets, which lapped and gurgled round the stem of their boat as they drove it gently through them. They did not hurry, and it was after one before they moored to the depot steps.

All was dark and silent above, as, carrying their purchases, they mounted to the wharf and crept stealthily to the barrel. Carefully they raised the lid, and Merriman, standing on the footstool, with some difficulty squeezed himself inside. Hilliard then lifted the footstool on to the rim and lowered the lid on to it, afterwards pa.s.sing in through the opening thus left the satchel of food and the one-inch auger.

A means of observation now remained to be made. Two holes, they thought, should afford all the view necessary, one looking towards the front of the wharf, and the other at right angles, along the side of the shed.

Slowly, from the inside, Merriman began to bore. He made a sound like the nibbling of a mouse, but worked at irregular speeds so as not to suggest human agency to anyone who might be awake and listening.

Hilliard, with his hand on the outside of the barrel, stopped the work when he felt the point of the auger coming through, and he himself completed the hole from the outside with his bradawl. This gave an aperture imperceptible on the rough exterior, but large within, and enabled the watcher to see through a much wider angle than he could otherwise have done. Hilliard then once more raised the lid, allowing Merriman to lift the footstool within, where it was destined to act as a seat for the observer.

All was now complete, and with a whispered exchange of good wishes, Hilliard withdrew, having satisfied himself by a careful look round that no traces had been left. Regaining the boat, he loosed the painter and pulled gently away into the night.

Left to himself in the confined s.p.a.ce and inky blackness of the cask, Merriman proceeded to take stock of his position. He was anxious if possible to sleep, not only to pa.s.s some of the time, which at the best would inevitably be terribly long, but also that he might be the more wakeful when his attention should be required. But his unusual surroundings stimulated his imagination, and he could not rest.

He was surprised that the air was so good. Fortunately, the hole through the lid which received the down spout was of large dimensions, so that even though he might not have plenty of air, he would be in no danger of asphyxiation.

The night was very still. Listening intently, he could not hear the slightest sound. The silence and utter darkness indeed soon became overpowering, and he took his watch from his pocket that he might have the companionship of its ticking and see the glimmering hands and ring of figures.

He gave himself up for the thousandth time to the consideration of the main problem. What were the syndicate people doing? Was Mr. Coburn liable to prosecution, to penal servitude? Was it possible that by some twist of the legal mind, some misleading circ.u.mstantial evidence, Miss Coburn--Madeleine--could be incriminated? Oh, if he but knew what was wrong, that he might be able to help! If he could but get her out of it, and for her sake Mr. Coburn! If they were once safe he could pa.s.s on his knowledge to the police and be quit of the whole business. But always there was this enveloping cloak of ignorance baffling him at every turn.

He did not know what was wrong, and any step he attempted might just precipitate the calamity he most desired to avoid.
