"No. But I should have come across them at any moment. The place isn't big enough to swing a cat in. Would you care to see it?"

"However small it may be, it's large enough to hold sixty bits of paper."

"Of course, everything is possible," said Dutreuil. "Still, I must repeat that nobody, to my knowledge, has been to my rooms; that there is only one key; that I am my own housekeeper; and that I can't quite understand...."

Hortense too could not understand. With her eyes fixed on Prince Rénine's, she was trying to read his innermost thoughts. What game was he playing? Was it her duty to support his statements? She ended by saying:

"Mr. Chief-inspector, since Prince Rénine maintains that the notes have been put away upstairs, wouldn't the simplest thing be to go and look? M. Dutreuil will take us up, won't you?"

"This minute," said the young man. "As you say, that will be simplest."

They all four climbed the five storys of the house and, after Dutreuil had opened the door, entered a tiny set of chambers consisting of a sitting-room, bedroom, kitchen and bathroom, all arranged with fastidious neatness. It was easy to see that every chair in the sitting-room occupied a definite place. The pipes had a rack to themselves; so had the matches. Three walking-sticks, arranged according to their length, hung from three nails. On a little table before the window a hat-box, filled with tissue-paper, awaited the felt hat which Dutreuil carefully placed in it. He laid his gloves beside it, on the lid.

He did all this with sedate and mechanical movements, like a man who loves to see things in the places which he has chosen for them. Indeed, no sooner did Rénine shift something than Dutreuil made a slight gesture of protest, took out his hat again, stuck it on his head, opened the window and rested his elbows on the sill, with his back turned to the room, as though he were unable to bear the sight of such vandalism.

"You're positive, are you not?" the inspector asked Rénine.

"Yes, yes, I'm positive that the sixty notes were brought here after the murder."
