"I don't blame you," he answered quietly. "I could, indeed, hope for no other reply. I must be quick, that's all. I must be very quick!"

Frobisher's anger fell away from him like a cloak one drops. He saw Hanaud sitting over against him with a white, desperately troubled face and eyes in which there shone unmistakeably some gleam of terror.

"Tell me!" he cried in an exasperation. "Be frank with me for once! Is Ann Upcott guilty? She's not alone, of course, anyway. There's a gang. We're agreed upon that. Waberski's one of them, of course? Is Ann Upcott another? Do you believe it?"

Hanaud slowly put his exhibits together. There was a struggle going on within him. The strain of the night had told upon them both, and he was tempted for once to make a confidant, tempted intolerably. On the other hand, Jim Frobisher read in him all the traditions of his service; to wait upon facts, not to utter suspicions; to be fair. It was not until he had locked everything away again in the safe that Hanaud yielded to the temptation. And even then he could not bring himself to be direct.

"You want to know what I believe of Ann Upcott?" he cried reluctantly, as though the words were torn from him. "Go to-morrow to the Church of Notre Dame and look at the façade. There, since you are not blind, you will see."

He would say no more; that was clear. Nay, he stood moodily before Frobisher, already regretting that he had said so much. Frobisher picked up his hat and stick.

"Thank you," he said. "Good night."

Hanaud let him go to the door. Then he said:

"You are free to-morrow. I shall not go to the Maison Crenelle. Have you any plans?"

"Yes. I am to be taken for a motor-drive round the neighbourhood."
