“Why, sir?”
“Because, Cardona, I have arranged to make a very valuable series of experiments. In going over your records, I find that your capability is unexcelled — so far as practical methods are concerned. Whatever theoretical ability you possess is chiefly intuitive.”
“I follow hunches,” said Cardona. “Is that what you mean?”
“Exactly,” resumed the commissioner warmly. “But you do not possess the faculty of analyzing those impressions. Usually, your practical methods come to your aid. But they have failed — and will always fail — when circumstances depend solely upon deductive reasoning.
“I do not hold to the opinion that theoretical reasoning is the proper method of combating crime. I do believe, however, that when baffling and unexplainable mysteries occur, the ideal detective must turn to deduction.
“Therefore, I intend to combine practice with theory. I have selected you as the practical man. I have also selected a man who should prove to be an excellent theorist.
“He is Professor Roger Biscayne, whose experiments in psychology have included an exhaustive study of the criminal mind.
“I do not consider Biscayne a detective; but I am positive that, as an analyst, he can produce remarkable results.
“I am withholding my experiment until some unusual crime occurs. Then I shall have Biscayne cooperate with you in its solution.”
As Weston finished speaking, he fancied that he saw resentfulness in Cardona’s eyes. The commissioner could understand it.
