Sherlock Holmes - The Second Highest Expert in Europe?

Sherlock holmes waved our strange visitor into a chair. The man drew out paper and tobacco and twirled the one up in the other with surprising dexterity. Holmes was silent, but his little darting glances showed me the interest which he took in our curious companion. I presume it is not merely for the purpose of examining my skull that you have done me the honor to call me here last night and again to day? No, sir, no, i came to you, mister holmes, because i am myself an unpractical man, and because i am suddenly confronted with a most serious and extraordinary problem.
