"Well, well, you did you best," said Holmes, as we walked into our room. "It's very annoying, though, Watson. I was badly in need of a case, and this looks, from the man's impatience, as if it were of importance. Hullo! That's not your pipe on the table. He must have left his behind him. A nice old brier with a good long stem of what the tobacconists call amber. I wonder how many real amber mouthpieces there are in London? Some people think that a fly in it is a sign. Well, he must have been disturbed in his mind to leave a pipe behind him which he evidently values highly."

"How do you know that he values it highly?" I asked.

"Well, I should put the original cost of the pipe at seven and sixpence. Now it has, you see, been twice mended, once in the wooden stem and once in the amber. Each of these mends, done, as you observe, with silver bands, must have cost more than the pipe did originally. The man must value the pipe highly when he prefers to patch it up rather than buy a new one with the same money."
