“Why?”

“Said he didn’t like the paper that was on.”

“And yet he could stand that frightful Cubist nightmare on the wall of the bedroom! H’m! Well, well! Very interesting—ve-ry interesting! See, Ziz?”

The black eyes of his little assistant sparkled. “Of course I do! He had the room papered in order to hide his precious recipe.”

“Right! Now, we may have to peel off the paper from the whole room,—for it’s not probable he kindly left it folded, in order to help us along.”

Dorcas listened with growing surprise. Here was a clever detective, indeed, to jump to this important conclusion,—if it was the true one.

“Let’s feel around,” Zizi said, and began passing her little brown paw over the walls.

“Not in plain sight, Ziz,” said Wise, and he started moving out a bookcase to look behind it.

They felt nothing that seemed like a paper behind the wall paper, but if the recipe had been placed without folding at all it would doubtless cause no appreciable extra thickness.

“Maybe he left a memorandum,” suggested Zizi, “or even a cryptogram in his desk telling where he hid it.”
