Sam's face was pale with apprehension that something had happened to Peter; but, he said, "How dat be, Massa Tom, with Sam in the next room all the time?"

Tom made no reply; but was closely examining the floor—back across the hall. "There is a mark; there is another," he said, "not made by boots, but by their native sandals." Then he went out from the door, and up the next flight of stairs.

"There," he said, "just as I thought." Just round the angle of the stairs two steps were dirty and stained, as if dirty feet had been trampling upon them for some time. "I suppose they knew I was out, and watched here, for hours, perhaps. Then, when Peter went down, they slipped in through the open door, and then"—without completing the sentence, Tom went back into the room, and threw himself into a chair in tearless despair.

Sam sobbed loudly. For some time there was silence. "There is no blood, sir, that I can see, not a speck," the orderly said. "They can't have killed Captain Scudamore, and, if they had, why should they have carried his body away?"

This was the question Tom had been asking himself. Assassinations were, in Madrid, every-day occurrences, and that Peter and he were especially liable to be murdered, owing to the hatred of Nunez and his gang, was clear; but, so far as he could see, not a drop of blood had been shed here. Presently Sam began to sob more loudly. "Dis break my heart, Massa Tom, to tink dat Sam be next door all de time, and, instead of watching, he sleep so sound dat Massa Peter carried straight away."

"You are not to blame, Sam, there was, probably, no noise whatever. But, what can it all mean? Johnstone, you had better go to bed, you can do no good now. Sam, give me my pistols; take that big stick of yours, and come round with me to head-quarters, we will call in at Captain Farquharson's on the way."

That officer, on being roused, and made to understand what was the matter, confirmed the account given by the orderly; he and his companions had parted at the street door, and Peter had gone down the yard to the stable.

"It is clear that Peter has been carried off," Tom said, "and I have not the least doubt that it has been done by some of the band of Nunez. As you have heard me say, they owe us a grudge, and have, no doubt, been on the look-out ever since we came here. We have been on guard, and never gave them a chance, and, I suppose, they got desperate when they found the army was moving again, and so carried out this audacious plan."

"If your brother had been found murdered I should understand it," Captain Farquharson said; "but, what on earth did they carry him off for?"

Tom was silent for a minute.
