The German-American was speaking. "Eversleigh?--that is His Grace's confidential servant--eh?" "That's the man. I studied Mr. Eversleigh by proxy, and I found out just two things about him." "And they were--what were they?" "One was that he was short-sighted, and the other was that he had a pair of spectacles which the duke had given him for a birthday present, and which he thought no end of." "That wasn't much to find out--eh?" "You think so? Then that's where you're wrong. It's perhaps just as well for you that you don't have to play first lead." "The treasury is more in my line--eh? However, what was the use which you made of that little find of yours?" "If it hadn't been for that little find of mine, the possibility is that the sparklers wouldn't be where they are just now. A friend of mine had a detective camera. Those spectacles were kept in something very gorgeous in cases. My friend snapped that spectacle case with his camera. I had an almost exact duplicate made of the case from the print he got--purposely not quite exact, you know, but devilish near.

Perhaps he would; anyhow, he lost something worth a trifle more than his arm. When he felt himself touched on the shoulder, and saw what looked like that almighty goggle-box in the stranger's hand, he got all of a flurry, jabbed his fist into the inside pocket of his coat, and to enable him to do so popped the despatch-box down on the seat beside him--as I expected that he would do. I happened to be sitting on that seat with a rug,
