The switch snapped, and in a few seconds the watcher saw Archer return to his office, bend for a moment over the lock of the door, then reseat himself at his desk.
“I’ve got them now,” he thought triumphantly. “I’ve got them at last. Tonight I’ll take them red-handed in whatever they’re doing.” He smiled in anticipation. “By Jove,” he went on, “it was lucky they sent nothing up last night, or they would have taken me red-handed, and that might have been the end of me!”
He was greatly impressed by the excellence of the telephone scheme. There was nothing anywhere about it to excite suspicion, and it kept Archer in touch with the illicit undertaking, while enabling him to hold himself absolutely aloof from all its members. If the rest of the organization was as good, it was not surprising that Hilliard and Merriman had been baffled.
But the puzzle was now solved, the mystery at an end. That night, so Willis assured himself, the truth would be known.
He remained in his hiding place all day, until, indeed, he had watched the workers at the distillery leave and the gray shadows of evening had begun to descend. Then he hid the telephone and wire in a cupboard, stealthily left the house, and after a rapid glance round hurried along the lane towards Ferriby.
He caught the 6.57 train to Hull, and in a few minutes was at the police station. There he saw the superintendent, and after a little trouble got him to fall in with the plan which he had devised.
As a result of their conference a large car left the city shortly before nine, in which were seated Inspector Willis and eight picked constables in plain clothes. They drove to the end of the Ferriby Lane, where the men dismounted, and took cover behind some shrubs, while the car returned towards Hull.
It was almost, but not quite dark. There was no moon, but the sky was clear and the stars were showing brightly. A faint air, in which there was already a touch of chill, sighed gently through the leaves, rising at intervals almost to a breeze, then falling away again to nothing. Lights were showing here and there—yellow gleams from unshaded windows, signal lamps from the railway, navigation lights from the river. Except for the sound of the retreating car and the dull roar of a distant train, the night was very still, a night, in fact, pre-eminently suitable for the inspector’s purpose.
The nine men moved silently down the lane at intervals of a few minutes, their rubber-shod feet making no sound on the hard surface. Willis went first, and as the others reached him he posted them in the positions on which he had previously decided. One man took cover behind the hedge of the lane, a short distance on the distillery side of the wharf, another behind a pile of old material on the railway at the same place, a third hid himself among some bushes on the open ground between the railway and the river, while a fourth crept as near to the end of the wharf as the tide would allow, so as to watch approaches from the water. When they were in position, Willis felt convinced no one could leave the syndicate’s depot for the distillery without being seen.
The other four men he led on to the distillery, placing them in a similar manner on its Ferriby side. If by some extraordinary chance the messenger with the “stuff” should pass the first cordon, the second, he was satisfied, would take him. He left himself free to move about as might appear desirable.
