"They are not much alike," I returned bluntly.

"Well, you see mine is a new one, and I'm not used to it yet. I hope you don't think I was trying to rob you?" he went on, with a look of reproach.

I was silent. I did think that that was just what he was trying to do, but I hardly cared to say so.

"It's awful to have such toothaches as I get," he continued, putting his hand to his cheek. "They come on me unawares, and drive me frantic. I wanted to get my teeth attended to in Jersey City when I was there, but I didn't have time."

"What's this on the handkerchief?" I asked.

"Oh, I guess I spilled some of my toothache cure on it," he replied, after some hesitation. "I used some and then put the bottle back in the valise. That's how I came to look for the bottle again. I hope you're not offended. It was all a mistake."

"It's all right if that's the case," I returned coolly.

Holding my valise on my lap, I settled back in the seat again, but not to sleep. The little adventure had aroused me thoroughly. Mr. Allen Price sat beside me for a few moments in silence.

"Guess I'll go into the smoker," he said finally, as he rose. "Maybe a cigar will help me," and taking up his handbag, he walked down the aisle.

In a dreamy way I meditated over what had occurred. I could not help but think that the handkerchief I had found spread over my face had been saturated with chloroform, and that my fellow-passenger had endeavored to put me in a sound sleep and then rifle my bag. Of course I might be mistaken, but still I was positive that Mr. Allen Price would bear watching.
