“Thus far you are coherence itself.”

“Well,” said Mr. White complacently, “I was a long time getting to work, Mr. Bruce, and had it not been for your help I should probably never have got at the truth, but I flatter myself that, once on the right track, I seldom leave it. However, as I was saying, I felt that Jane Harding knew a good deal more than she would tell, except under pressure, so I decided to put that pressure on.”

“In what way?”

“I frightened her. Played off on her a bit of the stage business she is so fond of. This afternoon I placed a pair of handcuffs in my pocket and went to her place at Bloomsbury, having previously prepared a bogus warrant for her arrest on a charge of complicity in the murder of Lady Dyke.”

“It was a dangerous game!”

“Very. If it had gone wrong and reached the ears of the Commissioner or got into the papers, I should have been reduced or dismissed. But what is a policeman to do in such cases? I was losing my temper over this infernal inquiry and never obtaining any real light, though always coming across startling developments. It had to end somehow, and I took the chance. The make-believe warrant and the production of handcuffs for a woman—they are never used, you know, in reality—have often been trump-cards for us when everything else failed.”

“This time, then, the ‘properties’ made up the ‘show,’ as Miss Harding would put it?”

“They did, and no mistake. I gave her no time to think or act. I found her sitting with her mother, admiring a new carpet she had just laid down. I said, ‘Is your name Jane Harding, now engaged at the Jollity Theatre, under the alias of Marie le Marchant, but formerly a maid in the service of Lady Dyke?’ She grew very white, and said ‘Yes,’ while her mother clutched hold of her, terrified. Then I whipped out the warrant and the cuffs. My, but you should have heard them squeal when the bracelets clinked together. ‘What has my child done?’ screamed the mother. ‘Perhaps nothing, madam,’ I answered; ‘but she is guilty in the eyes of the law just the same if she persists in screening the guilty parties.’ Jane Harding was trembling and blubbering, but she said, ‘It is very hard on me. I have done nothing.’ I trembled myself then, as I feared that she might offer to come with me to the police station, in which case I should have been dished. But the mother fixed the affair splendidly. ‘I am sure my daughter will not conceal anything,’ she said, ‘and it is a shame to disgrace her in this way without telling what it is you want to know.’ I took the cue in an instant. ‘I am empowered,’ I said, ‘to suspend this warrant, and perhaps do away with it altogether, if she answers my questions fully and truthfully.’ ‘Why, of course she will,’ said the mother, and the girl, though desperately upset, whimpered her agreement. With that I got the whole story.”

“Sir Charles Dyke inspired her actions, I suppose.”
