“A man’s meal,” he said with vast creature content. “Now give me that other half you have left. I want a shave. You go up and touch Dan for a five-spot. We may need expenses later. I’ll meet you at Dan’s at nine o’clock. I want to pick Monahan up again before I see you, and also see Leslie.”

At the time appointed we met. “Let’s take a ten-twenty-thirty,” suggested Lanagan. “By half-past ten we will have to get busy. There’s a singer over at the Continental that some of the dramatic critics say has real fire. La Pattini, I think she is called.”

So we drifted into the Continental and caught part of the performance. There were trained birds of more than ordinary sagacity; the stereotyped and fearful cornet soloist; the girl singer, La Pattini, with a wonderful mezzo, remarkable beauty, an undoubted future, and an ability to sing the “Rosary” in a manner to bring tears. Then came a slap-stick tumbling act that was impossible, and we left.

Lanagan had suddenly become thoughtful. “Do you know what I think?” he said. “I think the world would actually do better to sweep away every vestige of law and ordinance and make a clean start again. Our system of punishment is all wrong. Take one heinous class of crimes; we punish the individual who takes upon herself to punish. We say the State has the power of punishment and the prerogative; and yet in the very crimes that are the most damnable, the State can never interfere because the injured party must suffer in silence. You might as well expect children to learn English through hieroglyphics as to make applicable to present-day conditions the antiquated penal code to which society is harnessed. That’s about enough of the sermon stuff. It’s not in my line.”

Lanagan was taking the lead, but I was not altogether surprised when we finally found ourselves in the neighbourhood of the Northrup home. Nor was I altogether surprised when Chief Leslie, that shrewd and veteran thief-taker, suddenly stepped from a doorway. My mind shot ahead to the Northrup home, a few doors away, and I could not bring myself to believe it could be possible that she was a principal.

“Brady is above,” said Leslie. “He says she came in about twenty minutes ago. We had better move on her.”

“Immediately,” said Lanagan, and in a moment more we were all three before the door to a lower flat of the old-fashioned sort, with a bell jangling noisily as Lanagan pulled out the handle.

It was Miss Northrup who answered the ring. She had on a dressing gown, and her hair, I could see, had been taken down for retiring and then gathered in a loose coil on her head, probably when the bell rang. She opened the door but a few inches.

“We would like to speak with you a moment, Miss Northrup,” said Lanagan. He indicated the chief. “This is Chief Leslie.”

“Kindly permit us to enter,” said the chief. There was a shadow of authority in his tone, and I knew that Lanagan and the chief were planning a drive on the girl and that something would be stirring in this old-fashioned flat before long. She hesitated a moment and then threw the door wide open and motioned us into the parlour. In the hall a gas jet burned dimly, as though for some member of the family who was not yet home.
