"But what if she had put on the hat the wrong way?"

The feather slanted backward as it did in the photograph when the hat was put on properly. But if it was turned back to front, as Clara now had it, it slanted forward in a ridiculous manner.

There could be no mistake—the photograph had been tampered with!

"Yes," I answered, "it is all fraud and trickery."

"This is a very strange affair," said Monk, and began again to examine the hat which Clara had put in front of him.
