for a moment? That's the whole point and explanation of everything that has happened. The worst was over in a few seconds, in the thick of that awful fog, but, of course I never dreamt what I had done. I did think that I had knocked him out. But that was all that ever entered my head until this very morning."
"Were you close to your broken window at the time?"
"Very close, and yet out of sight in the fog."
"And you had seen nothing of this man Croucher, and his hand in the affair?"
"Not after I'd done my part. I did just before. I'm certain it was the same huge man that they describe. But I heard the whole thing while we were struggling. They were blowing a police-whistle and calling out 'Thieves!' I remember hoping that the policeman would hear them, and let me go. But I suppose his blood was up, as well as mine."
"And after you had – freed yourself?" said the doctor, trying not to set his teeth.
"I ran off, of course! I knew that I had done much more than I ever intended; but that's all I knew, or suspected, even when I found this horrid thing open in my hand. I tried to shut it again, but couldn't. So I hid it in my dress, and ran up Dover Street to my club, where I put it straight into a bag that I had there. Then I made myself decent and – turned out again with a proper hammer."
The doctor groaned; he could not help it. Yet it was his first audible expression of disapproval; he had restrained himself while all the worst was being told; and the girl's face acknowledged his consideration. Her color had come at last. Thus far, in recounting her intentional misdeeds, as though they were all in the great day's work, she had shown a divine indifference to his opinion of her or her proceedings. There had been nothing aggressive about it – he merely doubted whether the question of his views had ever entered her mind. But now he could see that it did; he had shown her something that she did not want to lose, and her fine candor hid that fact as little as any other.
"I didn't know what I'd done, remember!" she said with sharp solicitude. "I never did know until this morning, when I heard of the case for the first time, and for the first time saw the stains on the dagger – at which you've been trying so hard not to look! Do look at them, Doctor Dollar. Of course, there can be no doubt what they are, but I shall be only too glad for you to prove it to everybody's satisfaction."
"'Only too glad,' Lady Vera?"
They gazed at each other for several seconds. Her face was tragic to him now; but emotion, apparently, was the one thing she would condescend to hide. But for her eyes, she might have been incredibly callous and cold-blooded; her blue Irish eyes were great and glassy with a grief not soluble in tears.
"Doctor Dollar," she said, tensely, "nothing can undo this hideous thing, though I hope to live long enough to make such poor amends as a human being can. But in this other direction they must be made at once. It's no use thinking of what can't be undone till we have undone what we can – if we are quick! That's why I tried to go straight to the Home Secretary, and why I have come straight to you. Take me to him, Doctor Dollar, and help me to convince him that what I have told you is the whole truth and nothing else! If you think it will make it easier, satisfy yourself about those blood-stains. Then we can take the dagger with us."
The doctor applied a crude test on the spot. He stooped over the fire, heated the stained steel between the bars, cooled it at the open window, picked off a scale and examined it briefly under a microscope. All this was done with tremendous energy tempered by extreme precision and nicety. And Lady Vera followed the operation with an impersonal interest that could not but include the operator, so intent upon his task, so obviously thankful to have a task of any sort in hand. But when he rose from his microscope it was with a shrug of the shoulders, an almost angry shake of the head.
"Of course, this is all no good, you know!" he cried, as if it were her test. "It would take hours to make the analysis that's really wanted."
"But as far as you have gone, Doctor Dollar?"
"As far as I have gone – which isn't a legal or medical inch – it certainly does look like blood, Lady Vera."
"Of course it is blood. There's another thing that will help us, too."
"What's that?"
"One of the best points in the defense, so far as I've had time to make out, was about the prisoner's knife. Now, if we take this with us, either to the Home Secretary, or, if he still refuses to see me, to New Scotland Yard – "
"Lady Vera!" the doctor interrupted, aghast at her suicidal zeal. "Is it possible that you realize the position you are in? It isn't only a situation that you've got to face; that you have already done, superbly! But have you any conception of the consequences?"
"I think I have," said Lady Vera, smiling. "I don't believe they will hang me; it would be affectation to pretend I did. But, of course, that's their business – mine is to change places with an innocent man."
"That you will never do," replied the doctor warmly. "There's no innocent man in the case; this Croucher is a thief and a perjurer, besides being an old convict who has spent half his life in prison! He would have had five years for the other night's work, without any question of a murder; they'll simply pack him off to Dartmoor or Portland when we've saved his miserable neck. And save it we will, no fear about that; but at what a price – at what a price!"
"I don't see that you need trouble about it," said Lady Vera, concerned at his distress, "beyond putting me in touch with Mr. Vinson. The rest will be up to him, as they say; and, after all, it won't be anything so very terrible to me. I am an old prisoner myself, you must remember!"
There was a gleam of her notorious audacity with all this; but it was like the glow of flowers on a grave. The horror of things to happen had never possessed her valiant eyes, and yet it must have been there, for all at once Dollar missed it. He read her look. He had relieved her mind about the man in the cell, only to open it at last to the man in his grave. Grief crippled her as horror had not; prisons could be broken, but not the prison to which her hand had sent a fellow creature. Yet her grief was mastered in its turn, forced out of sight before his eyes, even while her flippant speech rang through him as the bravest utterance he had ever heard.
It blew a bugle in the man's brain, and the call was clear and definite. He knew his own mind only less instantaneously than he had penetrated hers. Never in all his days had he known his mind quite so well as when she thought better of the very words which had enlightened him, and went on to add to them in another key:
"So now, Doctor Dollar, will you crown all your great kindness by taking me to see the Home Secretary at once?"
"Lady Vera," he exclaimed, with unreasonable irritation, "what is the good of asking impossibilities? I couldn't take you to Topham Vinson even if I would. He would begin by doubting your sanity; there would be all manner of silly difficulties. Moreover, he's not in town."
She showed displeasure at the statement of fact only.
"Doctor Dollar, are you serious?"
"Perfectly."
"Have you forgot that I saw you together at almost two o'clock?"
"I think not quite so late as that. The Home Secretary left Euston at 2:45."
"Where for?"
She looked panic-stricken.
"I'll tell you, Lady Vera, if you promise not to follow him by the next train."
"When does it go?"
"Not for some time. There's only one more; we debated which he should take. But you mustn't take the other, Lady Vera; you must leave that to me. I want you to leave the whole thing to me – from this very moment till you hear from me again."
"When would that be, Doctor Dollar?"
"As soon as I have seen Mr. Vinson."
"You would undertake to tell him everything?"
"Every detail, exactly as you have told me."
"Will it seem credible at second-hand?"
"Quite enough so to justify a respite. That's the first object; and this is the first step to it, believe me! There's plenty of time between
