Mycroft Holmes

Sherlock Holmes' brother. Disinterested in my social affairs, Mycroft chastises his brother for not being analytical enough...so you know what type of character we're dealing with.

Book III:

He's visited by Mary, Diane, Watson and Beatrice who ask him for any help or leads that he may have to his brother. He summarily dismisses the lot of them, and tells Mary that he's heard she's resourceful, and she can figure it out.
