"Won't you sit down, Monsieur?" said Hilaire, in a tone of extreme politeness.

The Nut took the proffered chair. He grew more self-possessed. A smile flickered across Hilaire's face.

"You are quite out of breath. What happened to you, Monsieur?"

"Some ruffians were after me," returned the Nut. "They can't be far away. If I had not caught sight of the light under your door, and if you had net been sitting up so late, I don't know what would have become of me."

He ceased speaking. Furtive steps creeping along the pavement, and even the exchange of a few words in hushed whispers could be heard some five paces away from them. And then a great silence fell, but they were not deceived by it, and Hilaire said in an undertone:

"They're still there."

"Yes, they must have seen me come in. If that's so, they won't go away in a hurry."

"What do they want with you?"

"I can't tell you that."

"I've been too inquisitive. I apologize. I don't wish to know anything. I am entirely at your disposal, and ready to help you to the best of my ability. You said a word when you banged at my door which makes me your slave."
