"Because she has said that she would send it on the day when the betrothal was publicly proclaimed. That will be next Monday."

"Oh, then we have three days yet," said Holmes with a yawn. "That is very fortunate, as I have one or two matters of importance to look into just at present. Your Majesty will, of course, stay in London for the present?"

"Certainly. You will find me at the Langham under the name of the Count Von Kramm."

"Then I shall drop you a line to let you know how we progress."

"Pray do so. I shall be all anxiety."

"Then, as to money?"

"You have carte blanche."

"Absolutely?"

"I tell you that I would give one of the provinces of my kingdom to have that photograph."

"And for present expenses?"

The King took a heavy chamois leather bag from under his cloak and laid it on the table.

"There are three hundred pounds in gold and seven hundred in notes," he said.

Holmes scribbled a receipt upon a sheet of his note-book and handed it to him.

"And Mademoiselle's address?" he asked.

"Is Briony Lodge, Serpentine Avenue, St. John's Wood."

Holmes took a note of it. "One other question," said he. "Was the photograph a cabinet?"

"It was."

"Then, good-night, your Majesty, and I trust that we shall soon have some good news for you. And good-night, Watson," he added, as the wheels of the royal brougham rolled down the street. "If you will be good enough to call to-morrow afternoon at three o'clock I should like to chat this little matter over with you."
