His voice, which had been by no means so certain and confident as it was before, suddenly changed into a snarl of fury. The duke heard it without fear and with a sense of exultation. He knew that his serenity had gone home, that his contempt had stung even this wolf-pig man.

As if catching the infection of the note, the unseen ruffian behind the chair, who held his arms, gave them a sharp, painful wrench.

The men crowded round him. His legs were untied from the chair legs and then retied together. His arms were strongly secured behind him, and he was half pushed, half carried to a door at the back of the kitchen.

The leader of the gang went before, carrying a tallow candle in a battered tin holder.

Passing through the door, they came into a small back cellar-kitchen, in which there was a sink and a tap. A large tub, apparently used for washing, stood in one corner. Deft hands pulled this, half-full of greasy water as it was, away from where it originally stood.

A stone flag with an iron ring let into it was revealed.

A man pulled this up with an effort, revealing a square of yawning darkness, into which a short ladder descended. The leader went down first, and with some difficulty the helpless body of the duke was lowered down after him, though the depth could not have been more than eight feet or so.

When he had been pushed into this noisome hole the duke saw by the light of the candle which "Sidney" carried that he was in an underground chamber, perhaps some ten feet by ten. The walls were damp and oozing with saltpetre. The floor was of clay.

Looking up in the flickering light of the dip he could see where the ancient brick foundations of the house had been built into the ground. He was now, in fact, below the lowest cellar, in an unsuspected and forgotten chamber, left by the builders two hundred years ago.

"Now, this 'ere comfortable little detached residence, dook," said the man, "is where we generally puts our swag when it's convenient to keep it for a bit. Nobody knows of it. Nobody has ever learned of it. We discovered it quite by chance like. That man wot comes round and collects the rents ain't an idea of its existence. This 'ere is Rat Villa, this is. Now, good-night! 'Ope to see your lordship 'appy and 'ealthy in the morning! You will observe we have left you your right arm free to brush the vermin off."
