"The submarines come out of Pola. When they reach the line between the Balearics and the Spanish coast, they have oil for ten days' cruising, and then return to their base," he argued.

Now, if a submarine had been provisioned by José Medina in a creek of Mallorca, the ten days' cruise would be extended to three weeks. This had never happened. Moreover, the date fixed by Pontiana Tabor happened to fall precisely in the middle of one of those periods of three weeks during which the terror did not haunt those seas. Pontiana Tabor had not known enough. He had fixed his date at a venture.

"Yes," said Hillyard, rising from his chair. "I agree with you, Señor Ramon. Tabor is a liar. What troubled me was that I had no clue as to why he should lie. You have given me it, and with all my heart I thank you."

He shook the stevedore's hand and stood for a moment talking and joking with him upon other subjects. Hillyard knew the value of a smile and a jest and a friendly manner. Your very enemy in Spain will do you a good turn if you meet him thus. Then he turned to Baeza.

"I shall be back, perhaps, in a week, but perhaps not. I will let you know in the usual way."

The two men went down the stairs and into the street. It was empty now and black, but at the far end, as at the end of a tunnel, the Rambla blazed and roared and the crowds swung past like a procession.

"It is best that we should separate here," said Lopez Baeza, "if you have no further instructions."

"Touching the matter of those ships," Hillyard suggested.

"Señor Fairbairn has it in hand."

"Good. Then, my friend, I have no further instructions," said Hillyard. "I agree with you about Ramon. I will go first."
