One after another he examined the sheets which he had marked, starting with a hand-lens and then using one more powerful.  At the top of the table lay the specially prepared paper on which he had caught and preserved the marks in the dust of the Egyptian sarcophagus in the Museum.

Besides these things, I noticed that he had innumerable photographs, many of which were labelled with the stamp of the bureau in the Paris Palais de Justice, over which Bertillon had presided.

One after another he looked at the carbon prints, comparing them point by point with the specially prepared copy of the shoe-prints in the sarcophagus.  It was, after all, a comparatively simple job.  We had the prints of de Moche and Lockwood, as well as Whitney, all of them crossed by steps from Norton.

“Well, what do you think of that?” I heard him mutter.

I quit my typewriter, with a piece of paper still in it, and hurried into the main room.

“Have you found anything?”

“I should say I had,” he replied, in a tone that betrayed his own astonishment at the find.  “Look at that,” he indicated to me, handing over one of the sheets.  “Compare it with this Museum foot-print.”

With his pencil Kennedy rapidly indicated the tell-tale points of similarity on the two shoe-prints.

I looked up at him, convinced now of some one’s identity.

“Who was it?” I asked, unable to restrain myself longer.

Kennedy paused a minute, to let the importance of the surprise be understood.

“The man who entered the Museum and concealed himself in the sarcophagus in the Egyptian section adjoining Norton’s treasures,” replied Kennedy slowly, “was Lockwood himself!”

THE EVIL EYE

Completely at sea as a result of the unexpected revelation of the shoe-prints we had found in the Museum, and with suspicions now thoroughly aroused against Lockwood, I accompanied Kennedy to keep our appointment with the Senorita at the Prince Edward Albert.

We were purposely a bit early, in order to meet Inez, so that she would not have to be alone with the Senora, and we sat down in the lobby in a little angle from which we could look into the tea room.

We had not been sitting there very long when Kennedy called my attention to Whitney, who had just come in.  Almost at the same time he caught sight of us, and walked over.

“I’ve been thinking a good deal of your visit to me just now,” he began, seating himself beside us.  “Perhaps I should not have said what I did about your friend Norton.  But I couldn’t help it.  I guess you know something about that dagger he lost, don’t you?”

“I have heard of the ‘great fish’ and the ‘little fish’ and the ‘curse of Mansiche,’” replied Kennedy, “if that is what you mean.  Somehow the Inca dagger seems to have been mixed up with them.”
