The cabinet, or whatever I am to call it, has looked stolidly at me from the corner of the library for years. It is nothing more than a row of pigeon-holes in which I keep my secret papers. At least, the man who sold it to me recommended it for this purpose, dwelling lovingly as he did so upon the strength of the lock. So I bought it—in those first days (how far away!) when I came to London to set the Thames on fire.
