are right," he cried; "I am the King. Why should I attempt to
conceal it?"

"Why, indeed?" murmured Holmes. "Your Majesty had not spoken
before I was aware that I was addressing Wilhelm Gottsreich
Sigismond von Ormstein, Grand Duke of Cassel-Felstein, and
hereditary King of Bohemia."

"But you can understand," said our strange visitor, sitting down
once more and passing his hand over his high white forehead, "you
can understand that I am not accustomed to doing such business in
my own person. Yet the matter was so delicate that I could not
confide it to an agent without putting myself in his power. I
have come incognito from Prague for the purpose of consulting
you."

"Then, pray consult," said Holmes, shutting his eyes once more.

"The facts are briefly these: Some five years ago, during a
lengthy visit to Warsaw, I made the acquaintance of the well-known
adventuress, Irene Adler. The name is no doubt familiar to you."

"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.
