He went to the top of the stair, I following, ready to grab him if he tried to bolt. He stopped at a door in a dark passage, and knocked three times, then whispered, "Mum."

The door opened at once. I grasped two hands, and said, "How are you?" then slipped a pair of handcuffs over a woman's wrists.

I went inside and locked the door. I was in a regular trap, for I felt convinced there were some desperate characters in the house who would not stick at a trifle. There was not a moment to lose, so I dragged the woman to the window, threw the sash open, and whistled three times. My men popped their heads out of the door of the house I had left them in, saw me, and came up the lane at a rapid run.

In the meantime the woman screamed and alarmed the house. The door was burst open; a man rushed in and threw himself upon me. Just then, however, my three men ran forward and secured him in a trice.

I had made a haul. The net result was I had caught two fish that were worth catching. I am actually trying to make a pun, which is excusable, as my success was great. For the last twenty-four hours I had been as hard-faced as a dissenting chapel. There hadn't been a smile in me. The game was whist. There wasn't a "joker" in the pack. It was my deal now. I had turned up an honour, and had some good trumps in my hand.

The woman was the one I had followed the night before, and the man was the accomplice of "Thunder-and-Lightning" in the bank robbery. Notes were found in their possession, which were proved by the numbers to have been some of the stolen ones.

The prisoners were lodged in the nearest police station, much to my satisfaction. I walked away on the tips of my toes, and with my head held high. There was exhilaration in the air, and I felt as if I had swallowed a "pick-me-up."

As I returned to the office the conversation I had with Pat Kineen came fresh into my memory. How did he know I was "to go afther the biggest thafe of the wurrld" I should like to know? and why was his son acting as potboy in the hotel? Then Patsy's unguarded admissions pointed to something not yet cleared up. Pat had been got at. I had a bone to pick with him, and I would get into the marrow, so I gnawed away at it, ruminated over it, and digested it.

When I arrived at the office I saw that Pat had had some information of what had taken place. He was trying to hide something. His face looked scared and his hands shook.
