"I have no idea, father; they had Lion with them. He was asleep here when they called him from outside, and I saw him get up and dash through the open window."

"I can't understand it," the don said anxiously, "for the evening is cold; besides, they would scarcely go outside the garden after nightfall."

"They might be down at Chaquita's cottage, father."

"Oh, yes! I didn't think of that, Carlos," Don Ramon said. "Yes, they are often down at their old nurse's. Rosita, tell Juan to go down to Chaquita's cottage and beg the young ladies to return, as I want them."

In ten minutes the servant came back.

"They are not there, señor; they left there just as it was getting dark."

"Surely there is nothing to be uneasy about, Ramon!" his wife said. "The girls are often out as late as this on a moonlight evening. They are sure to be about the garden, somewhere."

"But Carlos has been round," Don Ramon said. "Well, we will go and have another look for them." Followed by the two young men he stepped out on to the verandah. "Carlos," he said, "go round to the men's quarters and tell them your sisters are missing, and that they are all to turn out and search. I don't like this," he said to Hugh, after his son had left. "I should have thought nothing of it at any other time, but after what you have just been telling me, I feel nervous. Now, let us go round the garden."
