He stirred his rum and water pointedly at me, and he tasted his rum and water pointedly at me.

And he stirred it and he tasted it; not with a spoon that was brought to him, but with a file.
He did this so that nobody but I saw the file; and when he had done it he wiped the file and put it in a breast-pocket.

I knew it to be Joe's file, and I knew that he knew my convict, the moment I saw the instrument.
