"And what was that?"

"That the person who wrote the note didn't know that Rogers was color-blind. You are welcome to that statement, too. You see, I'm treating you all alike."

They stood about me, staring down at me, silent with astonishment.

"But," I added, "I think Godfrey suspects what was in the note."

"Why?"

"Well, his theory fits it pretty closely."

"His theory! What is his theory, Mr. Lester?"

"Oh, come," I laughed. "That's telling. It's a good theory, too."

They looked at each other, and, I fancied, gnashed their teeth.

"He seems a pretty clever fellow," I added, just to pile up the agony. "I fancy you'll say so, too, when you see his theory in to-morrow's paper."
