tective, who had been sent out in
consequence of the bank robbery. He carefully scrutinised every
traveller, and if one of them bore any resemblance to the culprit he
would be arrested. Two days previously, Fix had received from London
the description of the criminal. It was that of the well-dressed
person who had been observed in the bank.

The detective was evidently inspired by the hope of obtaining the
large reward offered, and was awaiting the arrival of the _Mongolia_
with much impatience accordingly.

"So you say that the steamer is never behind its time," remarked Mr.
Fix to the Consul.

"No," replied the other. "She was signalled off Port Said yesterday,
and the length of the Canal is nothing to such a vessel as she is. I
repeat that the _Mongolia_ has always gained the twenty-five pounds
allowance granted by the Government for every advance of twenty-four
hours on the regulation time."

"Does she come from Brindisi direct?" asked Fix.

"Yes, direct. She takes the Indian mails on board there. She left on
Saturday afternoon at five o'clock. So be patient She will not be
late. But I really do not see how you will be able to recognise your
man from the description you have, even Supposing he be on board."

"One knows him by instinct more than by feature," replied Fix; "by
scent, as it were, more than sight. I have had to do with more than
one of these gentlemen in my time, and if the thief be on board I
guarantee he will not slip through my fingers."

"I hope you will catch him--it is a big robbery."

"First-rate," replied Fix enthusiastically; "fifty-five thousand
pounds. We don't often have such a windfall as that. These sort of
fellows are becoming scarce. The family of Jack Sheppard has died
out--people get 'lagged' now for a few shillings."

"You speak like an enthusiast, Mr. Fix," replied the Agent, "and I
hope you will succeed, but I fear under the circumstances you will
find it very difficult. Besides, after all, the description you have
received might be that of a very honest man."

"Great criminals always do resemble honest men," replied the detective
dogmatically. "You must understand that ruffianly-looking fellows
would not have a chance. They must remain honest or they would be
arrested at once. It is the honest appearance that we are obliged to
unmask; it is a difficult thing, I confess, and one that really is an
art."

It was evident that Mr. Fix thought a good deal of his profession.
