after he left Miss Fewbanks he flung aside his official pride in order to
discuss with Rolfe the enlistment of the services of Crewe. Rolfe was no
less indignant than his chief at the intrusion of an outsider into their
sphere. Crewe was an exponent of the deductive school of crime
investigation, and had first achieved fame over the Abbindon case some
years ago, when he had succeeded in restoring the kidnapped heir of the
Abbindon estates after the police had failed to trace the missing child.
In detective stories the attitude of members of Scotland Yard to the
deductive expert is that of admiration based on conscious inferiority,
but in real life the experts of Scotland Yard have the utmost contempt
for the deductive experts and their methods. The disdainful pity of the
deductive experts for the rule-of-thumb methods of the police is not to
be compared with the vigorous scorn of the official detective for the
rival who has not had the benefit of police training.

"Look here, Rolfe," said Inspector Chippenfield, "we mustn't let Crewe
get ahead of us in this affair, or we'll never hear the last of it. It's
scandalous of a man like Crewe, who has money of his own and could live
like a gentleman, coming along and taking the bread out of our mouths by
accepting fees and rewards for hunting after criminals. Of course I know
they say he is lavish with his money and gives away more than he earns,
but that's all bosh--he sticks it in his own pocket, right enough. One
thing is certain: he gets paid whether he wins or loses; that is to say,
he gets his fee in any case, but of course if he wins something will be
added to his fee. In the meantime all you and I get is our salaries, and,
as you know, the pay of an inspector isn't what it ought to be."

Rolfe assured his superior of his conviction that the pay at Scotland
Yard ought to be higher for all ranks--especially the rank and file. He
also declared that he was ready to do his best to thwart Crewe.
