"Yes, I thought his language seemed strange. But, you see, he did not speak in Basque, and we don't know much Spanish. Anyhow, we cannot do anything now. We will question him when he comes back again."

Highly satisfied with his success, Arthur walked on until he was challenged by a sentry ahead. He answered in English "A friend!", for he detected at once that the challenger belonged to the Legion.

"And who are you at all?" came from the sentry.

"I am one of your officers," he said. "Lieutenant Hallett. I have been in the Carlist camp."

"Come on, then, and let's have a look at ye. It is a mighty noise that they have been makin' up there."

"Yes; they have been having a scrimmage among themselves." He had now come up to the sentry.

"Well, sor, I can't see yes," the man said; "but it is clear that you are English, and that is good enough for me. Whether you are Lieutenant Hallett or not, I don't know; but I shouldn't be any wiser if I did see you, seeing that I don't know the gentleman. There are half a dozen of the boys down the hill with the sergeant at that house you can just make out fifty yards away. You had best go down to them and explain."

"All right, and good-night!" and Arthur walked on.

Arthur was passed without difficulty through the outposts, and when he reached the town he found that Sebastian had already returned to his own quarters.

"My dear friend," the latter exclaimed, springing to his feet, "I am delighted to see you. I have been in a terrible state of alarm as to your safety. I had just whispered to my cousin who I was, when there was a sudden uproar, and many of the guests ran out of the room suddenly. I looked round in vain for you. There was a general confusion, and five or six minutes later there was the sound of heavy firing, and all the rest of the guests made off in a great hurry. Of course I went out too, and waited till some of the company came back. None of them seemed to know exactly what had happened, but all were of opinion that a spy of some sort had been discovered at the wedding. He had been pursued, had run down through the lines, and a heavy fire had been opened upon him, and none doubted but that he was killed. Curiously enough, the men of the second line of defences had opened fire on those in the upper one. Why, no one knew. It could only be supposed that they believed that a Christino force had captured the upper line of trenches. I did not stop to hear later news, but made off to the boat in hopes of finding you there. I waited a quarter of an hour, as you told me, and then got in and floated down the river. I could not keep her to one side, as you did, and found that it was better to let her go as she liked. Fortunately there was such a stir in the Carlist camp that I passed down the river unobserved, and managed with a good deal of difficulty to get the boat ashore here. I have been back now about half an hour."
