back to its
manager, giving her address, for the sake of a shoe-buckle, even one set
with diamonds?"

"I'm not--for the moment--supposing that she is the thief," answered
Fullaway. "Why I want--and must--find her at once is to ask her a
simple question. What was she doing in James Allerdyke's room?
For--I've an idea."

"What?" demanded Allerdyke.

"This," replied Fullaway. "They were fellow-passengers on the _Perisco_.
Your cousin--as I daresay you know--was the sort of man who readily
makes friends, especially with women. My idea is that if this Miss
Lennard went into his room last night it was to be shown the Princess
Nastirsevitch's jewels. Your cousin was just the sort of man who knew how
a woman would appreciate an exhibition of such things. And--"

At that moment a waiter tapped at the sitting-room door and announced
Dr. Orwin.

CHAPTER VI

THE PRIMA DONNA'S PORTRAIT

Marshall Allerdyke's sharp eyes were quick to see that his new visitor
had something of importance to communicate and wished to give his news in
private. Dr. Orwin glanced inquiringly at the American as he took the
seat which Allerdyke drew forward, and the cock of his eyes indicated a
strong desire to know who the stranger was.

"Friend of my late cousin," said Allerdyke brusquely. "Mr. Franklin
Fullaway, of London--just as anxious as I am to hear what you have to
tell us, doctor. You've come to tell something, of course?"

The doctor inclined his head towards Fullaway, and added a grave bow in
answer to Allerdyke's question.

"The autopsy has been made," he replied. "By Dr. Lydenberg, Dr. Quillet,
who is one of the police-surgeons here, and myself. We made a very
careful and particular examination."

"And--the result?" asked Allerdyke eagerly. "Is it what you anticipated
from your first glance at him--here?"

The doctor's face became a shade graver; his voice assumed an
oracular tone.

"My two colleagues," he said, "agreed that your cousin's death resulted
from heart failure which arose from what we may call ordinary causes.
There is no need for me to go into details--it is quite sufficient to say
that they are abundantly justified in coming to the conclusion at which
they have arrived: it is quite certain that your cousin's heart had
recently become seriously affected. But as regards myself"--here he
paused, and looking narrowly from one to the other of his two hearers, he
sank his voice to a lower, more confidential tone
