Which of the Baker Street Regulars should I see?

Hint 1 of 7:

Guy Clarendon was part of high society.

Hint 2 of 7:

So see Langdale Pike for some background information.

Hint 4 of 7:

Try Porky Shinwell.

Hint 5 of 7:

Gerald Locke also told you that Frances was at the Old Bailey.

Hint 6 of 7:

See the barrister who's frequently at Old Bailey, Edward Hall.
