I was thinking to myself that I should like to see what the inside of the jail was like; Satan overheard the thought, and the next moment we were in the jail.

We were in the torture-chamber, Satan said.

The rack was there, and the other instruments, and there was a smoky lantern or two hanging on the walls and helping to make the place look dim and dreadful.

There were people there--and executioners--but as they took no notice of us, it meant that we were invisible.

A young man lay bound, and Satan said he was suspected of being a heretic, and the executioners were about to inquire into it.
