“You are right, my friend,” answered Roger. “But I do not intend that anybody shall catch us at this work; nor shall they catch sight of the tools. At the first sound of any person approaching you must jump down for your life, remove the stools, and sit down and pretend to be asleep. I will wrap the tools up quickly in their bag, and slip them into my jerkin. If we are summoned from the cell, and are likely to be searched, I shall endeavour, as we go, to drop the parcel behind the door, where it cannot be seen unless someone enters the cell and deliberately looks behind the door, which is not very likely unless they suspect us of having got hold of any tools. Now remember what I say. No more talk now, Harry; we shall require all our breath for working.”

They slaved away with file and saw, never ceasing work for a moment, until their muscles utterly refused to allow their tired arms to make another movement, and then they rested for a moment to recover. Harry and Roger each worked on a separate bar of the grating, and so equal had been their efforts that each lad’s bar was cut through at the same time.

“There go two nails drawn from our coffins, Roger,” said Harry, and he attacked his second bar with the energy born of deserved success. Roger uttered no word, but saved all his breath, and put every ounce of his strength into his arms, cutting away with file and saw like a very madman.

As the bars were cut out they were laid carefully on the sill in front of them, so as to be at hand for replacement directly any suspicious sound was heard. All night long they worked, and with such a will that soon after daybreak next morning but two bars remained to be cut through. As usual, an hour or two after dawn they heard the click of the trap as their food was placed in the cell; but it startled them only for a moment, for they had not overlooked the fact that their food was due to arrive. Moreover, they knew that the aperture was so small that there was but just room to pass a small platter through it, and that, even if the jailer should attempt to spy on them, the window was beyond his range of vision. The sound, however, recalled the fact to their minds that they were very hungry, and that if they wished to keep up their strength they must eat. And, as Harry said, they had done good work during the night, so that they could spare the time. The tools were therefore packed up and hidden away; the bars already cut were replaced so that anybody chancing to look in should notice nothing out of the ordinary; then the stools were removed from below the window, and both lads sat down to their morning meal with keener appetites than they had known for some months past. Everything in the cell presented its usual appearance, and the twain were hastily finishing their meal when the tramp of feet was heard in the passage. No quiet, stealthy footstep this time, but a clatter of several approaching men which there was no mistaking. Roger and Harry looked at one another, dismay written all over their countenances. What was to happen now? Had the hour for their execution been advanced again, and were they to be led out to death at once, or was their cell to be changed and all their labour rendered useless, and their chance of escape destroyed at the very last moment? These, and a hundred other surmises, chased each other rapidly through the lads’ minds as they listened with bated breath to the noise of the approaching footsteps. Each, however, pulled himself together, and by the time that the cell door was opened the lads presented absolutely expressionless faces to their enemies. The door clanged open, disclosing to their sight a number of men in black robes and cowls.

“His Excellency the Viceroy requires the attendance of you both,” said one of the masked inquisitors in a deep voice and in remarkably good English. “Follow me at once.”

The man turned to lead the way. Harry followed close on his heels; but as Roger prepared to leave the cell he pretended to stumble, and when picking himself up adroitly deposited the little satchel of tools behind the open door. His action, he was much relieved to notice, attracted no attention, and he had the satisfaction of seeing the cell door closed after them, and of knowing, therefore, that the precious implements were safe for the time being.

They were led through the self-same passages and corridors by which they had walked to the torture-chamber a few days before, and their hearts sank within them, for this second journey seemed to them ominous of evil.

Yes, it was but too true. In a few minutes they reached the door of that Chamber of Horrors, passed through it, heard it shut after them, and found themselves once more in the presence of that arch-fiend, Alvarez, “Viceroy of the Province, Governor of the City, and Chief of the Holy Inquisition in the town of Vera Cruz”. They were not long left in doubt as to what was in store for them. Alvarez spoke:

“I understand that you two young men formerly belonged to the squadron of that most pestilent heretic and pirate, Cavendish; is it not so? Answer me!”

“Yes,” replied Harry, “we belonged, and consider that we still belong, to the ship of Mr Cavendish, who is no pirate, but a noble and true English gentleman.”
