"How do you think Paul would look in this outfit?"

Roque indicated on the display rack a regulation English uniform of olive drab, with puttees, and a cap of the traditional French arms shape, but of khaki color.

Even if the boys had been in the mood to say that Zorn would look like the Eiffel tower in any sort of uniform, Roque gave them no time to break in upon his humor.

"Nothing like keeping up-to-date, young sirs, in my business. It was only a few weeks ago that this new style French soldier first appeared in Havre. And here we can make his mate in a minute or two."

This cat and mouse play was wearing on Billy and Henri. Free of anxiety, they might have enjoyed digging into the maze of disguises as they would the pages of a popular detective story, but they had a play of their own to make, and no chance yet to make it.

"Now, Paul, how will we fix up these young flyers for a bit of ground work? Something plain, yet neat, I think, will do for the sons of Doctor Blitz—I am Blitz to-morrow, I believe, Paul?"

Zorn simply showed his teeth. He was not expected to answer.

"Now, my bird boys, get out of those uniforms and I'll make a pair of likely students out of you. Do you prefer Heidelberg, the School of Arts, or the Conservatory? No matter, though, it is just a shift for a short journey, and I guess I can make you up to pass muster."

All the time Roque was chatting principally for the amusement of himself and Paul, his hands were busy sorting a pile of clothing and he was ready to start a couple of young Blitzes into society in the most finished style—from glazed cap to shiny shoes.
