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 this and – Tuesday."
"Oh! I know that," she returned, bluntly disdainful of a well-meant hesitation. "There's still not a moment to lose while that poor man lies facing death."
"I'm not sure that he does, Lady Vera. The decision's only just been made; it won't be out till the day after to-morrow. I don't believe they would break it to Croucher on Christmas Day."
"They can break the good news instead. Where is Mr. Vinson? It's all right, I won't attempt to tackle him till you have. That's a promise – and I don't break them like windows!"
John Dollar ignored that boast with difficulty. He saw through her tragic levity as through a glass, and his heart cried out with a sympathy hard indeed to keep to himself; but it was obviously the last thing required of him by Lady Vera Moyle. He gave her the required information in a voice only less well managed than her own. And he thought her eyes softened with the faintest recognition of his restraint.
"I thought the Duke had washed his hands of his notorious nephew," she remarked. "Well, we shall have to spoil the family gathering, I'm afraid."
"That's my job, Lady Vera."
"And I never thanked you for taking it on! Nor will I, Doctor Dollar; thanks don't meet a case like this!" Very frankly she took his hand instead: it was hotter and less steady than her own. "And now what about your train?"
"I'm afraid there's not one till seven o'clock. Vinson talked of going down by it at first."
The time-table confirmed his fear; he threw it down, and plunged into the telephone directory instead. Lady Vera watched him narrowly. He had dropped into his old oak chair, and the sheen of age on the table betrayed his face as though it were bent over clear brown water. She could see its anxiety as he had not allowed her to see it yet.
"I suppose you wouldn't care to face it in a motor?"
She was faltering for the first time.
"That's exactly what I mean to do," he answered, without looking up from the directory. "I'm just going to telephone for a car."
"Then you needn't!" she cried joyfully. "We have at least two eating their bonnets off in our mews. I'll go home in a taxi, and send one of them straight round with a driver who knows the way, and a coat that you must promise to wear, Doctor Dollar. All my people are away except my mother, and she won't know; she isn't strong enough to use the cars. But I mustn't speak of poor mother, or I shall make a fool of myself yet. It's partly my fault as it is, you see, and of course all this will make her worse. But I'm not so sure of that, either! My mother is the kind of person who has all the modern ailments and
