made him a sweeping bow.

"It is Dr. Spencer Whiles?" he asked.

The doctor admitted the fact and invited his visitor to enter.

"It is here, perhaps," the latter continued, "that a gentleman who was
riding a bicycle and was run into by a motor car, was brought after the
accident and treated so skilfully?"

"That is so," Dr. Whiles admitted. "There was nothing much the matter
with him. He had rather a narrow escape."

"I am that gentleman's servant," the visitor continued with a bland
smile. "He has sent me down here to see you. The leg which was injured
is perfectly well, but there was a pain in the side of which he spoke
to you, which has not disappeared. This morning, in fact, it is
worse,--much worse. My master, therefore, has sent me to you. He begs
that if it is not inconvenient you will return with me at once and
examine him."

The doctor drew a little breath. This might mean another week or so of
respite!

"Where does your master live?" he asked the man.

"In the West end of London, sir," was the reply. "The Square of St.

Dr. Whiles glanced at his watch.

"It will take me some time to go there with you," he said, "and I shall
have to arrange with a friend to treat any other patients. Do you think
your master will understand that I shall need an increased fee?"

"My master desired me to say," the other answered, "that he would be
prepared to pay any fee you cared to mention. Money is not of account
with him. He has not had occasion to seek medical advice in London,
and as he is leaving very soon, he did not wish to send for a strange
physician. He remembered with gratitude your care of him, and he sends
for you."

"That's all right," Dr. Whiles declared, "so long as it's understood.
You'll excuse me for a moment while I write a note, and I'll come
along."

Dr. Whiles had no note to write, but he made a few changes in his toilet
which somewhat improved his appearance. In due course he reappeared and
was rapidly whirled up to London, the sole passenger in the magnificent
car. The man who had brought him the message from his quondam patient
was sitting in front, next the chauffeur, so Dr. Whiles had no
opportunity of asking him for any information concerning his master. Nor
did the car itself slacken speed until it drew up before the door of the
large corner house in St. James' Square. A footman in dark livery came
running out; a butler bowed upon the steps. Dr. Spencer Whiles
