Quotation from: The Adventures of Sherlock Holmes

Written by: Sir Arthur Conan Doyle

"God bless you! You are doing what you can for him and for me.
But it is too heavy a task. What was he doing there at all? If
his purpose were innocent, why did he not say so?"

"Precisely. And if it were guilty, why did he not invent a lie?
His silence appears to me to cut both ways. There are several
singular points about the case. What did the police think of the
noise which awoke you from your sleep?"
