It was Giuseppe’s turn to show surprise now.

“With your assistance I’ll get this man and the whole gang to-night,” explained Craig, rapidly sketching over his plan and concealing just enough to make sure that no matter how anxious the lieutenant was to get the credit he could not spoil the affair by premature interference.

The final arrangement was that four of the best men of the squad were to hide in a vacant store across from Vincenzo’s early in the evening, long before anyone was watching.  The signal for them to appear was to be the extinguishing of the lights behind the coloured bottles in the druggist’s window.  A taxicab was to be kept waiting at headquarters at the same time with three other good men ready to start for a given address the moment the alarm was given over the telephone.

We found Gennaro awaiting us with the greatest anxiety at the opera-house.  The bomb at Cesare’s had been the last straw.  Gennaro had already drawn from his bank ten crisp one-thousand-dollar bills, and already had a copy of Il Progresso in which he had hidden the money between the sheets.

“Mr. Kennedy,” he said, “I am going to meet them to-night.  They may kill me.  See, I have provided myself with a pistol—­I shall fight, too, if necessary for my little Adelina.  But if it is only money they want, they shall have it.”

“One thing I want to say,” began Kennedy.

“No, no, no!” cried the tenor.  “I will go—­you shall not stop me.”

“I don’t wish to stop you,” Craig reassured him.  “But one thing—­ do exactly as I tell you, and I swear not a hair of the child’s head will be injured and we will get the blackmailers, too.”

“How?” eagerly asked Gennaro.  “What do you want me to do?”

“All I want you to do is to go to Albano’s at the appointed time.  Sit down in the back room.  Get into conversation with them, and, above all, Signor, as soon as you get the copy of the Bolletino turn to the third page, pretend not to be able to read the address.  Ask the man to read it.  Then repeat it after him.  Pretend to be overjoyed.  Offer to set up wine for the whole crowd.  Just a few minutes, that is all I ask, and I will guarantee that you will be the happiest man in New York to-morrow.”

Gennaro’s eyes filled with tears as he grasped Kennedy’s hand.  “That is better than having the whole police force back of me,” he said.  “I shall never forget, never forget.”

As we went out Kennedy remarked:  “You can’t blame them for keeping their troubles to themselves.  Here we send a police officer over to Italy to look up the records of some of the worst suspects.  He loses his life.  Another takes his place.  Then after he gets back he is set to work on the mere clerical routine of translating them.  One of his associates is reduced in rank.  And so what does it come to?  Hundreds of records have become useless because the three years within which
