my excuses, escaped from the house. I hesitated whether to
attempt to secure the photograph at once; but the coachman had
come in, and as he was watching me narrowly it seemed safer to
wait. A little over-precipitance may ruin all."

"And now?" I asked.

"Our quest is practically finished. I shall call with the King
to-morrow, and with you, if you care to come with us. We will be
shown into the sitting-room to wait for the lady, but it is
probable that when she comes she may find neither us nor the
photograph. It might be a satisfaction to his Majesty to regain
it with his own hands."

"And when will you call?"

"At eight in the morning. She will not be up, so that we shall
have a clear field. Besides, we must be prompt, for this marriage
may mean a complete change in her life and habits. I must wire to
the King without delay."

We had reached Baker Street and had stopped at the door. He was
searching his pockets for the key when someone passing said:

"Good-night, Mister Sherlock Holmes."

There were several people on the pavement at the time, but the
greeting appeared to come from a slim youth in an ulster who had
hurried by.
