He wondered how it came that Mackay had not at the time recognised the Vanes as a wanted couple. Probably, he thought, the man had been so much occupied with his own case that he had not read up the particulars in the _Bulletin_, which, after all, was a magazine intended more for the rank and file than for men on specialised duties. However, the fact remained that Mackay had missed his chance, though his habit of detailed observation had enabled him to some extent to redeem his error. But if it was true that the Vanes had not left the ship at Liverpool, what became of the statements of the Captain and Purser? It was not likely that these men could be hoodwinked over such a matter. They were experts; moreover, they were dealing with a ship with whose every part they were familiar. To the Vanes, on the other hand, the ship would be strange, and they would be ignorant of its routine. Under these circumstances it was absolutely out of the question that the pair could have hidden themselves on board. No, if they were there, the Captain would have known of it. French could not devise any explanation of the matter. The whole thing seemed a contradiction. He had, however, to settle his own plans. The kindly French police officer had helped him by ’phoning the local office of the Booth Line and finding out the itinerary of the _Enoch_. This was Saturday, and on the afternoon of the following day, Sunday, the steamer was expected to reach Leixoes, the port of Oporto. She would remain there that night and the next day, leaving Leixoes about 8 o’clock on the Monday evening. Next day about noon she was due in Lisbon, where she would remain for two days. After that her first call was Madeira. French had intended to meet her in Lisbon, but it now occurred to him that he might be able to make Oporto in time to join her there. He had bought a railway guide in Havre, and he now proceeded to look up the trains. The route, he saw, was to Bordeaux by the Paris-Orleans line, then on by the Midi to the Spanish frontier at Irun, and so by Medina and Salamanca to Oporto. The first through train from Paris after their arrival at 4.35 p.m. was the 10.22 p.m. from the Gare Quai d’Orsay, and this reached Oporto at shortly after midday on the next day but one, Monday. Oporto to Leixoes was only half an hour’s run, so he had six or seven hours’ margin. Oporto, he decided, was his goal. They were fortunate in securing sleeping berths between Paris and Bordeaux, and there was a restaurant car on the train to Irun. They waited an hour at the frontier station, and French blessed the intelligence of Manning, who had had their identification papers made available for Spain and Portugal as well as France.
