Holmes Trivia 3

Hey everyone! Thanks for sticking around :)

Amy reminded me of a project I started awhile back...the Holmes Trivia. Heh, I kinda forgot about it until she said something. So...here's round 3!

Remember, no using search engines. Try to answer everything from your own knowledge. If you need to, you may refer to your copy of the canon or other books that might contain information. But yeah...Google and Yahoo! make everything entirely too easy to access. If you need to refresh your memory on the rules, please click here. Again, ONLY use the canon if you absolutely need to.

1) In a case from "The Adventures of Sherlock Holmes," Holmes, Watson, a man named Mr. Merryweather and a policeman wait in a bank vault. What is the name of the case and the policeman?

2) In a case from "The Adventures of Sherlock Holmes," Holmes goes to the prison to visit a beggar man who was being held there. What is the name of the case and who is the beggar man?

3) What is the name of Watson's librarian friend who helps him to find a book on Chinese pottery?

Good luck! Post your answers in a comment and I will come back within the next few days to post the answers :)
