"Now for Osborne," whispered Furneaux. "Leave him to me, Winter. Trust me implicitly for five minutes—that is all."

Osborne was brought in by the station inspector, that human ledger who would record without an unnecessary word the name of the Prime Minister or the Archbishop of Canterbury on any charge preferred against either by a responsible member of the force. The young American was calm now, completely self-possessed, disdainful of any ignominy that might be inflicted on him. He did not even glance at Furneaux, but nodded to Winter.

"Your assurances are seemingly of little value," he said coldly.

"Mr. Winter is quite blameless," snapped Furneaux, obviously nettled by the implied reproof. "Please attend to me, Mr. Osborne—this affair rests wholly between you and me. Learn now, for the first time, I imagine, that Rose de Bercy was my wife."

Osborne did truly start at hearing that remarkable statement. Clarke's mouth literally fell open; even the uniformed inspector was stirred, and began to pare a quill pen with a phenomenally sharp knife, this being the only sign of excitement he had ever been known to exhibit.

"Yes, unhappily for her and me, we were married in Paris soon after she ran away from home," said Furneaux. "I—I thought—we should be happy. She had rare qualities, Mr. Osborne; perhaps you discovered some of them, and they fascinated you as they fascinated me. But—she had others, which I learnt to my sorrow, while you were spared. I cannot explain further at this moment. I have only to say that you are as free from the guilt of her death—as I am!"

Winter alone was conscious of a queer note in the little man's voice as he dwelt on the comparison. He seemed to be searching for some simile of wildest improbability, and to have hit upon himself as supplying it. But Osborne was in no mood for bewilderment. He cared absolutely nothing about present or future while the horrible past still held the pall it had thrown on his prospects of bliss with Rosalind.

"In that event, one might ask why I am here," he said quietly. "Not that I am concerned in the solving of the riddle. You have done your worst, Mr. Furneaux. You can inflict no deeper injury on me. If you have any other vile purpose to serve by telling me these things, by all means go right ahead."

Furneaux's eyes glinted, and his wizened cheeks showed some token of color, but he kept his voice marvelously under control.

"In time you will come to thank me, Mr. Osborne," he said. "To-day you are bitter, and I am not surprised at it, but you could never have been happy in your marriage with Miss Rosalind Marsh while the shadow of suspicion clung to you. Please do not forget that the world believes you killed Rose de Bercy. If you walked forth now into Regent Street, and the word went around that you were there, a thousand people would mob you in a minute, while ten thousand would be prepared to lynch you within ten minutes. I have played with you, I admit—with others, too, and now I am sorry—to a certain extent. But in this case, I was at once detective, and judge, and executioner. If you wantonly transferred your love from the dead woman to the living one, I cared not a straw what you suffered or how heavily you were punished. That phase has passed. To-day you have justified yourself. Within twenty-four hours you will be free to marry Rosalind Marsh, because your name will have lost the smirch now placed on it, while your promise to Hylda Prout will be dissolved. But for twenty-four hours you must remain here, apparently a prisoner, in reality as much at liberty as any man in London. Yes, I vouch for my words——" for at last wonder and hope were dawning in Osborne's eyes—"my chief, Mr. Winter, will tell you that I have never spoken in this manner without making good what I have said—never, I repeat. If I could spare you the necessity of passing a night in a cell I would do so; but I cannot. You are the decoy duck for the wild creature that I mean to lay hands on before another day has closed. Make yourself as comfortable as possible—the inspector will see to that—but I must keep you here, a prisoner in all outward semblance. Are you willing?"
