“You must not go down here,” he said, in a husky voice, barring the passage with his arm.

“Why not?”

“Go up again!” said Steinmetz breathlessly. “You must not go down here.”

Paul laid his hand on the broad arm stretched across the stairway. For a moment it almost appeared to be a physical struggle, then Steinmetz stepped aside.

“I beg of you,” he said, “not to go down.”

And Paul went on, followed by Steinmetz, and behind them, Maggie. At the foot of the stairs a broader passage led to the side door, and from this other passages opened into the servants’ quarters, and communicated through the kitchens with the modern building.

It was evident that the door leading to the grassy slope at the back of the castle was open, for a cold wind blew up the stairs and made the lamps flicker.

At the end of the passage Paul stopped.

Steinmetz was a little behind him, holding Maggie back.

The two lamps lighted up the passage and showed the white form of the Princess Etta lying huddled up against the wall. The face was hidden, but there was no mistaking the beautiful dress and hair. It could only be Etta. Paul stooped down and looked at her, but he did not touch her. He went a few paces forward and closed the door. Beyond Etta a black form lay across the passage, all trodden underfoot and dishevelled. Paul held the lamp down, and through the mud and blood Claude de Chauxville’s clear-cut features were outlined.
