The day following this one, about four o'clock in the afternoon, Joseph discovered a dynamite cartridge containing a pound and a half of the explosive in the vestibule at the front door. The fuse of this cartridge was already alight and would have reached and exploded the percussion, or detonating cap, if Joseph, for some reason unknown, had not gone to the front door at that moment. He was not called there, and had not heard anybody in the vestibule, or on the steps, and Joseph forever insisted after this incident that it was an intervention of Providence.

This last incident was extremely serious, for had the cartridge been exploded it must have torn away the entire front of the house, and have done enormous damage, even if it had taken no lives.

Friday night of that week at about half-past eight o'clock in the evening Chick and Patsy were walking up Madison Avenue together, and when they arrived at the corner of Thirtieth Street, and were about to turn toward Fifth Avenue, a shot was fired at them from across the street.

Fortunately the bullet did not strike either of them; and, although they both immediately pursued the would-be assassin, he was evidently prepared to avoid them, for he leaped upon a bicycle and sped away so swiftly that there was no hope of overtaking him. They only saw that he was tall and slender, and that was all.

The Saturday morning following an express wagon stopped at Nick Carter's house and delivered a package addressed to the detective, which was marked: "Fragile. This side up, with care."

Joseph carried it to the detective's study, placed it upon the table, and was about to leave the room when Nick stopped him.

"What is that, Joseph?" he asked.

"An express package, sir, which just came for you."

"Who brought it, Joseph?"

"The express wagon, sir."
