Mr Williamson

He was a respectable, elderly gentleman.
“Williamson is a white-bearded man, and he lives alone with a small staff of servants at the Hall. There is some rumor that he is or has been a clergyman, but one or two incidents of his short residence at the Hall struck me as peculiarly unecclesiastical.”

“I have already made some inquiries at a clerical agency, and they tell me that there was a man of that name in orders, whose career has been a singularly dark one.” (Sherlock Holmes)
