"We shall have to clear from here," said Hal, looking round at the row of rough pallets which evidently served the soldiers for beds. "What about the roof? Perhaps we can reach it this way."
He ran into a room at the back of the building, and, climbing on to a window-sill, stretched his arm above his head. It was too short by a couple of feet, and the gutter looked hopelessly out of reach. Suddenly, however, he thought of the latticed shutter, and grasping the battens, and digging his feet in between those below, hoisted himself up. A moment later he had one hand on the iron gutter, and after that had no difficulty in clambering on the roof, which ascended at an easy slope.
"Hand up the grub, Gerald," he said, leaning over the edge and lowering his voice to a gentle whisper. "That's it. Let go; I've got hold of the handle. Now, up you come."
Gerald was as active as a monkey, and quickly climbed to Hal's side, when the two scrambled along the roof till they arrived at a part where the coping formed with the sloping tiles a deep angle; and here they lay full length, settling themselves into the narrow space, and taking particular pains to make sure that no part of their dress was projecting over the top. Down below in the yard there was the clatter of many feet as the soldiers ran round the building. Then the same voice that had answered the questions of the sentry was heard again, calling loudly.
"There is a bucket lying over here," the man cried, "but we can see no trace of anyone. Are you sure you are not mistaken?"
"I distinctly heard someone fall," was the answer. "Idiot! Do you think that I could make an error when it occurred so close at hand? Am I not on duty? One would think that I was a log by the way in which you talk. Mistaken, indeed! How do you know that it is not those beggarly prisoners whom we are to waste powder upon to-morrow morning? Perhaps it is they, and while you chatter and tell your comrade that he does not do his duty, they may be escaping."
The sentry bellowed out his words, and snorted with indignation, for his feelings were evidently hurt at such an accusation. But the other man was not to be subdued.
"Escaping? Ridiculous, Santo!" he cried. "They were locked in the cell. I was one of the guard, and saw it with my own eyes. Perhaps you will tell me next that these American spies are capable of flying through a locked door!"
"I tell you that I am sure that someone is attempting to get away from the castle, and I believe it to be the two prisoners who came here this evening," the sentry answered angrily. "Give the alarm, comrade, and hurry off to make sure of the matter. Do not let the cause of our country suffer because we cannot agree."
The soldier in the yard below grumbled; but, urged on by his comrades, who seemed to agree with the sentry, he hastened to the castle, and Hal and his companion heard him running up the flight of stone steps.
