"At the present moment she's sleeping in your best guest room," he said. "I gave her enough of your sleeping tablets to keep her like that till breakfast time."

Nordsten looked at him.

"And where is Sardon?" he asked at length.

"He is in his laboratory."

Nordsten poured himself out a Dr.ink and sat down.

"Tell me," he said.

Simon told him the story. When he had finished, Nordsten was silent for a while. Then he said: "It's all right, of course. A fire like that must have destroyed all the evidence. It could all have been an accident. But what about the girl?"

"I told her that her uncle had locked the door and refused to let me in. Her evidence will be enough to show that Sardon was not in his right mind."

"Would you have done it anyhow, Simon?"

The Saint nodded.
