I dared ask her no questions. I fancied that each scene brought back its own memories, but not the ideas associated with the chain of scenes.

We secured adjacent rooms at the château, and leaving Jacqueline to unpack her things, and under instructions not to leave her room and promising to return as soon as possible, I started out at once to find Maclay & Robitaille's.

This proved a task of no great difficulty. It was a little shop where leather goods were sold, situated on St. Joseph Street. A young man with a dark, clean-shaven face, was behind the counter. He came forward courteously as I approached.

"I have come on an unusual mission," I began foolishly and stopped, conscious of the inanity of this address. What a stupid thing to have said! I must have aroused his suspicions immediately.

He begged my pardon and called a man from another part of the shop. And that gave me my chance over again, for I realized that he had not understood my English.

"Do you remember," I asked the newcomer, "selling a collar to a young lady recently—no, some long time ago—a dog-collar, I mean?"

The proprietor shrugged his shoulders. "I sell a good many dog-collars during the year," he answered.

I took the plate from my pocket and set it down on the counter. "The collar was set with silver studs," I said. "This was the plate." Then I remembered the name Leroux had used and flung it out at random. "I think it was for a Mlle. Duchaine," I added.

The shot went home.

"Ah, monsieur, now I remember perfectly," answered the proprietor, "both from the unusual nature of the collar and from the fact that there was some difficulty in delivering it. There was no post-office nearer the seigniory than St. Boniface, where it lay unclaimed for a long time. I think madamoiselle had forgotten all about the order. Or perhaps the dog had died!"
