Quotation from: The Adventures of Sherlock Holmes

Written by: Sir Arthur Conan Doyle

"Kindly look her up in my index, Doctor," murmured Holmes without
opening his eyes. For many years he had adopted a system of
docketing all paragraphs concerning men and things, so that it
was difficult to name a subject or a person on which he could not
at once furnish information. In this case I found her biography
sandwiched in between that of a Hebrew rabbi and that of a
staff-commander who had written a monograph upon the deep-sea
fishes.
