He rang a bell and a blue-coated man opened the door.  “Call Herman, Jim,” he said, then, as the man disappeared, he went on to us, “I have given Herman carte-blanche instructions to conduct a thorough investigation.  He has been getting the goods on another swell joint on the next street, in Forty-eighth, a joint that is just feeding on young millionaires in this town, and is or will be the cause of more crime and broken hearts if I don’t land it and break it up than any such place has been for years.”  The door opened, and Dillon said, “Herman, shake hands with Mr. Garrick and Mr. Marshall.”

The detective was a quiet, gentlemanly sort of fellow who looked rugged and strong, a fighter to be respected.  In fact I would much rather have had a man like him with us than against us.  I knew Garrick’s aversion to the regular detective and was not surprised that he did not overwhelm Mr. Herman by the cordiality of his greeting.  Garrick always played a lone hand, preferred it and had taken Dillon into his confidence only because of his official position and authority.

“These gentlemen are going to work independently on that Rena Taylor case,” explained Dillon.  “I want you to give Mr. Garrick every assistance, Herman.”

Garrick nodded with a show of cordiality and Herman replied in about the same spirit.  I could not fancy our getting very much assistance from the regular detective force, with the exception of Dillon.  And I noticed, also, that Garrick was not volunteering any information except what was necessary in good faith.  Already I began to wonder how this peculiar bargain would turn out.

“Just who and what was Rena Taylor?” asked Garrick finally.

Inspector Herman shot a covert glance at Dillon before replying and the commissioner hastened to reassure him, “I have told Mr. Garrick that she was one of our best stool pigeons and had been working on the gambling cases.”

Like all detectives on a case, Herman was averse to parting with any information, and I felt that it was natural, for if he succeeded in working it out human nature was not such as to willingly share the glory.

“Oh,” he replied airily, “she was a girl who had knocked about considerably in the Tenderloin.  I don’t know just what her story was, but I suppose there was some fellow who got her to come to New York and then left her in the lurch.  She wasn’t a New Yorker.  She seems to have drifted from one thing to another—­until finally in order to get money she came down and offered her services to the police, in this gambling war.”

Herman had answered the question, but when I examined the answer I found it contained precious little.  Perhaps it was indeed all he knew, for, although Garrick put several other questions to him and he answered quite readily and with apparent openness, there was very little more that we learned.

“Yes,” concluded Herman, “someone cooked her, all right.  They don’t take long to square things with anyone who raps to the ‘bulls.’”
