“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.”
