Approaching a table whereon were displayed a number of torture implements, he selected a pair of gigantic pinchers that had been specially designed for tampering with human anatomy, and applied them vigorusly to the nuts which fixed the spikes of the Iron Maiden.

"Otto the Hunchback little knew that his chef d'œuvre would be put to such a benevolent purpose as a refuge," he said, as he loosened and withdrew the spikes one by one from their rusty environment. "Given ten minutes' respite, and I'll guarantee a hiding-place no one in his senses will dream of searching."

"Quick, quick, quick!" cried the Princess in a crescendo of excitement, transformed again from a pale, hunted creature to a gleeful schoolgirl playing a particularly exciting game of hide-and-seek. "I hear them searching the other rooms. Quick!"

Trafford deposited the last spike in the pocket of his overcoat, and motioned to his companion to enter. When she had done so, he closed the doors, locked them, and put the key into his pocket with the spikes.

"Are you all right?" he asked.

"Quite comfy, thanks," answered a muffled voice.

Trafford contemplated the exterior of the Iron Maiden, and was pleased to note air-holes in the Maiden's ears. It had not been the intention of the mediæval tormentor that his victims should die of suffocation.

A few moments later there was the tread of martial steps along the passage, and the door was thrown open. Trafford buried himself in the contemplation of a water-funnel that had served to inconvenience human stomachs with an intolerable amount of fluid.

"Herr Trafford once again!"

The gentleman addressed looked up and beheld the grey-coated figure of General Meyer. Behind him with drawn swords were two officers of the Guides.
