Beamish and Bulla were to travel by the 4 p.m., and Willis, carefully disguised as a deep-sea fisherman, watched them arrive separately, take their tickets, and enter the train. Beamish travelled first, and Bulla third, and again the inspector had their tickets examined, and found they were for London.

Archer was to leave at 5.3, and Willis intended as a precautionary measure to travel up with him and keep him under observation. Still in his fisherman’s disguise, he took his own ticket, got into the rear of the train, and kept his eye on the platform until he saw Archer pass, suitcase and rug in hand. Then cautiously looking out, he watched the other get into the through coach for King’s Cross.

As the train ran past the depot at Ferriby, Willis observed that the Girondin was not discharging pit-props, but instead was loading casks of some kind. He had noted on the previous Friday, when he had been in the neighborhood, that some wagons of these casks had been shunted inside the enclosure, and were being unloaded by the syndicate’s men. The casks looked like those in which the crude oil for the ship’s Diesel engines arrived, and the fact that she was loading them unemptied—he presumed them unemptied—seemed to indicate that the pumping plant on the wharf was out of order.

The 5.3 p.m. ran, with a stop at Goole, to Doncaster, where the through carriage was shunted on to one of the great expresses from the north. More from force of habit than otherwise, Willis put his head out of the window at Goole to watch if anyone should leave Archer’s carriage. But no one did.

At Doncaster Willis received something of a shock. As his train drew into the station another was just coming out, and he idly ran his eye along the line of coaches. A figure in the corner of a third-class compartment attracted his attention. It seemed vaguely familiar, but it was already out of sight before the inspector realized that it was a likeness to Benson that had struck him. He had not seen the man’s face and at once dismissed the matter from his mind with the careless thought that everyone has his double. A moment later they pulled up at the platform.

Here again he put out his head, and it was not long before he saw Archer alight and, evidently leaving his suitcase and rug to keep his seat, move slowly down the platform. There was nothing remarkable in this, as no less than seventeen minutes elapsed between the arrival of the train from Hull and the departure of that from London, and through passengers frequently left their carriage while it was being shunted. At the same time Willis unostentatiously followed, and presently saw Archer vanish into the first-class refreshment room. He took up a position where he had a good view of the door, and waited for the other’s reappearance.

But the distiller was in no hurry. Ten minutes elapsed, and still he made no sign. The express from the north thundered in, the engine hooked off, and shunting began. The train was due out at 6.22, and now the hands of the great clock pointed to 6.19. Willis began to be perturbed. Had he missed his quarry?

At 6.20 he could stand it no longer, and at risk of meeting Archer, should the latter at that moment decide to leave the refreshment room, he pushed open the door and glanced in. And then he breathed freely again. Archer was sitting at a table sipping what looked like a whisky and soda. As Willis looked he saw him glance up at the clock—now pointing to 6.21—and calmly settle himself more comfortably in his chair!

Why, the man would miss the train! Willis, with a sudden feeling of disappointment, had an impulse to run over and remind him of the hour at which it left. But he controlled himself in time, slipped back to his post of observation, and took up his watch. In a few seconds the train whistled, and pulled majestically out of the station.

For fifteen minutes Willis waited, and then he saw the distiller leave the refreshment room and walk slowly down the platform. As Willis followed, it was clear to him that the other had deliberately allowed his train to start without him, though what his motive had been the inspector could not imagine. He now approached the booking-office and apparently bought a ticket, afterwards turning back down the platform.
