er see this Dr. Tretheway," he remarked.

Dr. Tretheway, an elderly man of grave manners and benevolent aspect,
remembered the visit of Mr. Marston Greyle well enough when he had turned
up its date in his case book. He also remembered the visitor's companion,
Mr. Chatfield, who seemed unusually anxious and concerned about Mr.
Greyle's health.

"And as to that," continued Dr. Tretheway, "I learnt from Mr. Greyle that
he had been seriously indisposed for some months before setting out for
England. The voyage had been rather a rough one; he had suffered much
from sea-sickness, and, in his state of health, that was unfortunate for
him. I made a careful examination of him, and I came to the conclusion
that he was suffering from a form of myocarditis which was rapidly
assuming a very serious complexion. I earnestly advised him to take as
much rest as possible, to avoid all unnecessary fatigue and all
excitement, and I strongly deprecated his travelling in one journey to
the north, whither I learnt he was bound. On my advice, he and Mr.
Chatfield decided to break that journey at Bristol, at Birmingham, and at
Leeds. By so doing, you see, they would only have a short journey each
day, and Mr. Greyle would be able to rest for a long time at a stretch.
But--I formed my own conclusions."

"And they were--what?" asked Gilling.

"That he would not live long," said the doctor. "Finding that he was
going to the neighbourhood of Norcaster, where there is a most excellent
school of medicine, I advised him to get the best specialist he could
from there, and to put himself under his treatment. But my impression was
that he had already reached a very, very serious stage."

"You think he was then likely to die suddenly?" suggested Gilling.

"It was quite possible. I should not have been surprised to hear of his
death," answered Dr. Tretheway. "He was, in short, very ill indeed."

"You never heard anything?" inquired Gilling.

"Nothing at all--though I often wondered. Of course," said the doctor
with a smile, "they were only chance visitors--I often have
trans-atlantic passengers drop in--and they forget that a physician would
sometimes like to know how a case submitted to him in that way has
turned out. No, I never heard any more."

"Did they give you any address, either of them?" asked Copplestone,
seeing that Gilling had no more to ask.

"No," replied the doctor, "they did not. I knew of course, from what
they told me that Mr.
