"Can you not see? Indeed, one might fairly have objected to your presence also. But you are a man. There is an implied horror of the darkest sort for poor Mary in the suggestion that Hardcastle may still live. If he can be brought back to life, then she would surely think that perhaps her husband and your son might have been. Imagine the agony of that. I speak plainly; indeed, there is no rational or sentimental reason why I should not, for the truth is, of course, that the signs of death were clearly evident on your poor boy before what we had to do was done. But the bare thought must have shocked Mary. We know emphatically that Hardcastle is dead, and we need not mention to her this fantastic theory from London."

"I appreciate your consideration," said Sir Walter; and the clergyman also acknowledged it.

"There can be no shadow of doubt concerning my son," he said; "nor is there any in the matter of this unfortunate man."

Henry Lennox went to prepare for the journey. Then, obeying the doctor's directions and treating the dead man as though he were merely unconscious, they carried him to the ambulance car. It was an unseemly farce in Mannering's opinion, and he only realized the painful nature of his task when he came to undertake it; but he carried it through in every particular as directed, conveyed the corpse to Newton after dark, and had the ambulance bed, in which it reposed, borne to the saloon carriage when the night mail arrived from Plymouth, between eleven and twelve. He was able to regulate the temperature with hot steam, and kept hot bottles to the feet and sides of the dead.

He felt impatient and resentful; he poured scorn on the superior authority for the benefit of the inspector and Henry Lennox, who accompanied him; but in secret he experienced emotions of undoubted satisfaction that life had broken from its customary monotonous round to furnish him with an adventure so unique. He pointed out a fact to the policeman before they had started.

"You will observe," he said, with satire, "that, despite the heat we are directed to apply to this unfortunate man, rigor mortis has set in.

Whether the authority in London regards that as an evidence of death, of course I cannot pretend to say. Perhaps not. I may be behind the times."

Neither Mannering nor Lennox had spared much thought for those left behind them at Chadlands. The extraordinary character of the task put upon them sufficed to fill their minds, and it was not until the small hours, when they sat with their hands in their pockets and the train ran steadily through darkness and storm, that the younger spoke of his cousin.

"I hope those old men won't bully Mary to-night," he said. "I'd meant to ask you to give Uncle Walter a caution. May's not quite all there, in my opinion, and very likely, now you're out of the way, he'll get round Sir Walter about that infernal room."

Mannering became interested.

"D'you mean for an instant he wants to try his luck after what's happened?"

"You forget. Your day has been so full that you forget what did happen."

"I do not, Lennox. Mary begged me to tackle the man. I calmed him, and he came down to his luncheon. He must have thought over the matter since then, and seen that he was playing with death."

"Far from it, 'The future is mine!' That's what he said. And that means he'll try and be in the Grey Room alone to-night."

"I wish to Heaven you'd made this clear before we'd started. But surely we can trust Sir Walter; he knows what this means, even if that superst.i.tious lunatic doesn't."

"I don't want to bother you," answered Henry; "but, looking back, I'm none so sure that we can trust my uncle. He's been pretty wild to-day, and who shall blame him? Things like this crashing into his life leave him guessing. He's very shaken, and has lost his mental grip, too.

Reality's played him such ugly tricks that he may be tempted to fall back on unreality now."

"You don't mean he'll let May go into that room to-night?"

"I hope not. He was firm enough last night when the clergyman clamored to do so. In fact, he made me keep watch to see he didn't. But I think he's weakened a lot since Hardcastle came to grief in broad daylight.

And I sha'n't be there to do anything."

"All this comes too late," answered the other. "If harm has happened--it has happened. We can only pray they've preserved some sanity among them."

"That's why I say I hope they're not bullying Mary," answered Lennox.

"Of course, she'd be dead against her father-in-law's idea. But she won't count. She can't control him if Sir Walter goes over to his side."

"Let us not imagine anything so unreasonable. We'll telegraph to hear if all's well at the first moment we can."

The storm sent a heavy wash of rain against the side of the carriage. It was a famous tempest, that punished the South of England from Land's End to the North Foreland.

They were distracted from their thoughts by the terrific impact of the wind.

"Wonder we can stop on the rails," said Mannering. "This is a fifty-knot gale, or I'm mistaken."

"I'm thinking of the Chadlands trees," answered the other. "It's rum how, in the middle of such an awful business as this, the mind switches off to trifles. Does it on purpose, I suppose, to relieve the strain.

Yes, the trees will catch it to-night. I expect I shall hear a grim tale of fallen timber from Sir Walter by the time I get back to-morrow."

"If nothing's fallen but timber, I sha'n't mind," answered Mannering; "but you've made me devilish uneasy now. If anything further went wrong--well, to put it mildly, they would say your uncle ought to have known a great deal better."

"He does know a great deal better. It's only that temporarily he's knocked off his balance. But I hardly feel as anxious as you do. There's Mary against May; and even if my uncle were for him, on a general, vague theory of something esoteric and outside nature, which you can't fairly call unreasonable any more, Mannering, seeing what's happened--even if Sir Walter felt tempted to let him have his way, I don't believe he'd really consent when it came to the point."

"I hope not--I hope not," answered the other. "Such a concession would take a lot of explanation if the result were another of these disasters.

There ought to be an official guard over the room."

"After to-morrow there certainly will be," replied Henry. "You may be sure the police won't leave it again till they've satisfied themselves.

All the same, I don't see how a dozen of them will be any safer than one--even if it's some material and physical thing that happens, as we must suppose. And for that matter, if it's really supernatural, why should a dozen be safer than one? Obviously they wouldn't. Whatever it is, it can strike as it likes and without being struck back."

But Dr. Mannering did not answer these questions. He was considering a little book in his pocket, which he would hand over to the police in London next morning.

"Poor chap--if he could have begun by taking the problem by the throat, as he has written here. But, instead, it took him by the throat!"

He took Hardcastle's notebook from his pocket and read again the last few pages.

"He was dreaming of his theories to the last, when he should surely have been girt up in every limb to face facts," said Lennox. "He never realized the horrible danger."

Perusal of the detective's data had revealed an interesting fact. It was known by his colleagues that he designed a book on the theory and practice of criminal investigations, and in many of his pocket-books, subsequently examined, were found memoranda and jottings, doubtless destined to be worked out at another time. It was clear that he had, for a few moments, drifted away from the Grey Room in thought when his death overtook him. Past events, not present problems, were apparently responsible for the reflections that occupied his mind. He was not concentrating on the material phenomena actually under his observation when he died, but following some private meditations provoked by his experiences.

"Elimination embraces the secret of success," he had written. "Exercise the full force of your intelligence and spare no pains to eliminate from every case all matter not bearing directly upon the actual problem. Nine times out of ten the issue is direct, and once permit side issues to draw their tracks across it, once admit metaphysical lines of reasoning, the result will be confusion and a problem increasing in complexity at every stage. Only in romances, where a plot is invented and then complicated by deliberate art, shall we find the truth ultimately permitted to appear in some subordinate incident, or individual, studiously kept in the background--that is the craft of telling detective stories. But, in truth, one needs to lay hold of the problem by the throat at the outset. Deception is too much the province of the criminal and too little the business of the investigator; and where it may be possible to creep, like a snake, into a case, unknown for what you truly are, then your opportunities and chances of success are enormously increased. It is, however, the exception when one can start without the knowledge of anybody involved, and the Scotland Yard of the future will pursue its business under very different circ.u.mstances from the present. The detective's work should be made easier and not more difficult. None should know who is working on a case. The law's representatives should be disguised and move among the characters surrounding the crime as something other than they really are. They will--"

Here Hardcastle's reflections came to an end. Some previous notes there were of superficial accidents in the Grey Room and a rough ground plan of it; but nothing more. He had evidently, for the time being, broken away from his environment and was merely thinking, with a pen on paper, when he died.

CHAPTER VII. THE FANATIC

A succession of incidents, that must have perturbed the doctor and his companion in earnest, had followed upon their departure from Chadlands, and Mary soon discovered that she was faced with a terrible problem.

For one young woman had little chance of winning her way against an old man and the religious convictions that another had impressed upon him.

Sir Walter and the priest were now at one, nor did the common sense of a fourth party to the argument convince them. At dinner Septimus May declared his purpose.

"We are happily free of any antagonistic and material influence," he said. "Providence has willed that those opposed to us should be taken elsewhere, and I am now able to do my duty without more opposition."

"Surely, father, you do not wish this?" asked Mary. "I thought you--"

But the elder was fretful.

"Let me eat my meal in peace," he answered. "I am not made of iron, and reason cuts both ways. It was reasonable to deny Mr. May before these events. It would be unreasonable to pretend that the death of Peter Hardcastle has not changed my opinions. To cleave to the possibility of a physical explanation any longer is mere folly and obstinacy. I believe him to be right."

"This is fearful for me--and fearful for everybody here. Don't you see what it would mean if anything happened to you, Mr. May? Even supposing there is a spirit hidden in the Grey Room with power and permission to destroy us--why, that being so, are you any safer than dear Tom was or this poor man?"

"Because I am armed, Mary, and they were defenseless. Unhappily youth is seldom clothed in the whole armor of righteousness. My dear son was a good and honorable man, but he was not a religious man. He had yet to learn the incomparable and vital value of the practice of Christian faith. Hardcastle invited his own doom. He admitted--he even appeared to pride himself upon a crude and pagan rationalism. It is not surprising that such a man should be called away to learn the lessons of which he stood so gravely in need."
