"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 d.y.k.e."

"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 d.y.k.e?' 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 d.y.k.e inspired her actions, I suppose."

"From the very beginning almost. At first Jane Harding herself believed, when she gave evidence at the inquest, that the body she saw was not that of Lady d.y.k.e; but afterwards she changed her opinion, especially when she recalled the exact pattern and materials of the underclothing.

Then my inquiries put her on the scent. Being rather a sharp girl, she jumped to the conclusion that Sir Charles knew more about the matter than he professed. In any case, her place was gone, and she would soon be dismissed, so she resolved on a plan even bolder than mine in threatening to lock her up. She watched her opportunity, found Sir Charles alone one day, and told him that from certain things within her knowledge, she thought it her duty to go to the police-station. He was startled, she could see, and asked her to explain herself. She said that her mistress had been killed, and she might be able to put the police on the right track. He hesitated, not knowing what to say; so she hinted that it would mean a lot of trouble for her, and she would prefer, if she had 500, to go to America, and let the matter drop altogether. He told her that he did not desire to have Lady d.y.k.e's name brought into public notoriety. Sooner than to allow such a thing to occur he would give her the money. An hour later he handed her fifty ten-pound notes."

"What a wretched mistake," cried Bruce involuntarily. This unmasking of his unfortunate friend's duplicity was the most painful feature of all to him.

"Perhaps it was," replied the detective, "but the thing is not yet quite clear to me. That is why I am here. But to continue. The girl admitted that she lost her head a bit. Instead of leaving the house openly, without attracting comment, she simply bolted, thus giving rise to the second sensational element attending Lady d.y.k.e's disappearance. But she resolved to be faithful to her promise. When you found her she held her tongue, and even wrote to Sir Charles to a.s.sure him that she had not spoken a word to a soul. He sent for her, and pitched into her about not going to America, but took her address in case he wished to see her again."

"He recognized her letter-writing powers, no doubt."

"Evidently. She was surprised last Thursday week to receive a telegram asking her to meet him at York Station. When she arrived there he asked her to write the letter he handed to you and to post it in London on Sat.u.r.day evening. He explained that his action was due to his keen anxiety to shield his wife's name, and that this letter would settle the affair altogether. As he handed her another bundle of notes, and promised to settle 100 a year on her for life, she was willing enough to help him. During your interview with her you guessed the reason why she wrote Lady d.y.k.e's hand so perfectly. She had copied it for three years."

"All this must have astonished you considerably?"

"Mr. Bruce, astonished isn't the word. I was flabbergasted! Once she started talking I let her alone, only rattling the handcuffs when she seemed inclined to stop. But all the time I felt as if the top of my head had been blown off."

"I imagine she had not much more to tell you?"

"She pitched into you as the cause of all the mischief, and went so far as to say that she was sure it was not Sir Charles who killed Lady d.y.k.e, but you yourself."

Bruce winced at Jane Harding's logic. Were he able to retrieve the past three months the mystery of Lady d.y.k.e's death would have remained a mystery forever.

"Now about the photograph," said the detective. "After I had left Jane Harding with a solemn warning to speak to no one until I saw her again, I made a round of the fashionable photographers and soon obtained an excellent likeness of Sir Charles. I showed it to Dobson, and she said: 'That is Colonel Montgomery.' I showed it to the foreman of the furniture warehouse, and he said: 'That is the image of the man who ordered Mrs. Hillmer's suite.' Now, what on earth is the upshot of this business to be? I called at Wensley House, but was told Sir Charles was not in town. Had he been in, I would not have seen him until I had discussed matters with you."

"That is very good of you, Mr. White. May I ask your reason for showing him this consideration?"

The policeman, who was very earnest and very excited, banged his hand on the table as he cried:

"Don't you see what all this amounts to? I have no option but to arrest Sir Charles d.y.k.e for the murder of his wife."

"That is a sad conclusion."

"And do you believe he killed her?"

"Strange as it may seem to you, I do not."

"And I'm jiggered if I do either."

"I--I am greatly obliged to you, White."

Claude bent his head almost to his knees, and for some minutes there was complete silence. When he again looked at the detective there were tears in his eyes.

"What can we do to unravel this tangled skein without creating untold mischief?" he murmured.

"It beats me, sir," was the perplexed answer. "But when I came in I imagined that Jane Harding or some one had been to see you. Surely, you had learned something of all this before my arrival?"

"Yes, indeed. I had reached your goal, but by a different route.

Unfortunately, my discovery only goes to confirm yours."

Bruce then told him of his visit to the lawyer's office, and its result.

Mr. White listened to the recital with knitted brows.

"It is very clear," he said, when the barrister had ended, "that Lady d.y.k.e was killed in Mrs. Hillmer's flat, that Sir Charles knew of her death, that he himself conveyed the body to the river bank at Putney, and that ever since he has tried to throw dust in our eyes and prevent any knowledge of the true state of affairs reaching us."

"Your summary cannot be disputed in the least particular."

"Well, Mr. Bruce, we must do _something_. If you don't like to interfere, then _I_ must."

"There is but one person in the world who can enlighten us as to the facts. That person obviously is Sir Charles d.y.k.e himself."

"Unquestionably."

Bruce looked at his watch. It was 10.30 P.M. He rose.

"Let us go to him," he said.

"But he is not in London."

"He is. I expect you will find that he gave orders for no one to be admitted, and told the servants to say he had left town to make the denial more emphatic."

"It will be a terrible business, I fear, Mr. Bruce."

"I dread it--on my soul I do. But I cannot shirk this final attempt to save my friend. My presence may tend to help forward a final and full explanation. No matter what the pain to myself, I must be present. Come, it is late already!"

CHAPTER XXVIII

SIR CHARLES d.y.k.e'S JOURNEY

The streets were comparatively deserted as they drove quickly up Whitehall and crossed the south side of Trafalgar Square. It is a common belief, even among Londoners themselves, that the traffic is dense in the main thoroughfares at all hours of the night until twelve o'clock has long past.
