London, at the time that he laughed at my not going to Mawson's, I happened to notice that his tooth was stuffed in this very identical fashion. The glint of the gold in each case caught my eye, you see. When I put that with the voice and figure being the same, and only those things altered which might be changed by a razor or a wig, I could not doubt that it was the same man. Of course you expect two brothers to be alike, but not that they should have the same tooth stuffed in the same way. He bowed me out, and I found myself in the street, hardly knowing whether I was on my head or my heels. Back I went to my hotel, put my head in a basin of cold water, and tried to think it out. Why had he sent me from London to Birmingham? Why had he got there before me? And why had he written a letter from himself to himself? It was altogether too much for me, and I could make no sense of it. And then suddenly it struck me that what was dark to me might be very light to Mr. Sherlock Holmes. I had just time to get up to town by the night train to see him this morning, and to bring you both back with me to Birmingham."
There was a pause after the stock-broker's clerk had concluded his surprising experience. Then Sherlock Holmes cocked his eye at me, leaning back on the cushions with a pleased and yet critical face, like a connoisseur who has just taken his first sip of a comet vintage.
"Rather fine, Watson, is it not?" said he. "There are points in it which please me. I think that you will agree with me that an interview with Mr. Arthur Harry Pinner in the temporary offices of the Franco-Midland Hardware Company, Limited, would be a rather interesting experience for both of us."
"But how can we do it?" I asked.
"Oh, easily enough," said Hall Pycroft, cheerily. "You are two friends of mine who are in want of a billet, and what could be more natural than that I should bring you both round to the managing director?"
