"He'd be safe anywhere. The question in my mind is whether our silver's safe; and a few other things. I catched him poking about in the silver table only this morning. He knows what's what. He knows everything. I wouldn't say he ain't one of the swell mob myself--made up to look like an old man. I'll swear he's never seen eighty years for all he pretends."

Henry laughed.

"Don't you be frightened of him, Masters; he's all right."

"Let him go in the Grey Room by all means, Mr. Henry. He knows he's safe anywhere. Yes, Sir Walter, he knows he's safe enough. He's got the measure of it."

"Prince is to go with him, Masters."

"Prince! Why, ma'am?"

"We don't know. He wishes it. He can't hurt poor old Prince anyway."

"Well, I sha'n't sleep no worse; and I hope none of you won't, if you'll excuse me. Come what will, there's nothing in the Grey Room will catch that man napping. Not that I'm against the gentleman in general, you understand. Only I wouldn't trust him a foot. He's play-acting, and he's no more a foreigner than I am--else he couldn't talk so fine English as I do, if not finer."

"Masters is on our side, father," said Mary. "And he's right. The signor is play-acting. He loves to be in the centre of the stage. All old people do, and one of the pathetic things in life is that they're seldom allowed to be. So he's making the most of his opportunity."

"And if you refuse, Uncle Walter, he'll only go away and say he cannot help you, and accuse us of giving him all this trouble for nothing,"

added Henry Lennox.

They had their wish at last, and when Signor Mannetti came down to an early dinner in splendid spirits, Sir Walter conceded his desire.

"Good, my friend! And do not fear that a night of anxiety awaits you.

Indeed, if I am not mistaken, it will be possible for us all to sleep very soundly, though we may go to bed rather late. But I think we must be prepared not to retire till after two o'clock. I will enter upon my watch at eight--in half an hour. The door shall be left open, as you wish. But I beg that none will approach the east end of the corridor.

That is only fair. I will, however, permit Mr. Lennox to station himself on the top of the great staircase, and from time to time he may challenge me. He shall say 'Is all well?' and be sure I shall answer 'All is well.' Could anything be more satisfactory?"

Signor Mannetti ate sparingly, then he donned a big, fur, motor-coat and declared himself ready. They thought he had forgotten Prince, but he insisted upon the company of the ancient spaniel. The dog had fed, and he could sleep as well in one place as another.

"Fear not," said the Italian. "I shall be considerate to your ancient pet. I do not beg his aid without reason. He is on my side and will help me if he can--infirm though he be. I have made friends with him. Set him at my feet. I will sit here under the electric light and read my Italian papers."

Thus once again a solitary occupied the Grey Room and measured his intelligence against the terrible forces therein concealed. Signor Mannetti took leave of them cheerfully at eight o'clock, and while Sir Walter and Mary descended to the library, Henry took up his station at the head of the staircase. The corridor was lighted and the door of the Grey Room left open.

But in ten minutes the watcher looked out and cried to Lennox, who sat smoking about thirty-five yards from him.

"There is a great draught here," he said. "I will close the door, but leave it ajar that we may salute each other from time to time."

The hours crept on and since everybody at Chadlands knew what was happening, few retired to rest. It was understood that some time after midnight Signor Mannetti hoped to declare the result of his experiment.

Henry Lennox challenged half-hourly, always receiving a brisk reply.

But a little after half-past one his "All well, signor?" received no response. He raised his voice, but still no answer came. He went to the door, therefore, and looked into the Grey Room. The watcher had slipped down in the armchair they had set for him under the electric light, and was lying motionless, but in an easy position. He still wore his fur-coat. Prince Henry did not see. The room was silent and cold. The electric light burned brightly, and both windows were open. Young Lennox hastened downstairs. His thoughts concentrated on his uncle, and his desire was to spare him any needless shock. For a moment he believed that Signor Mannetti had succ.u.mbed in the Grey Room, as others before him, but he could not be certain. A bare half-hour had elapsed since the watcher had uttered a cheerful answer to the last summons, and told them his vigil was nearly ended. Lennox sought Masters, therefore, told him that the worst was to be feared, yet explained that the old man who had watched in the Grey Room might not be dead but sunk in sleep.

Masters was sanguine that it might be so.

"Be sure he is so. I'll fetch the liqueur brandy," and, armed with his panacea, he followed Henry upstairs. Signor Mannetti had not moved, but as they approached him, to their infinite relief he did so, opened his eyes, stared wildly about him, and then realized the situation.

"Alas! Now I have frightened you out of your senses," he said, looking at their anxious faces. "All is well. In less than another hour I should have summoned Sir Walter. But just that last half-hour overcame me, and I sank into sleep. What is the time?"

"A quarter to two, signor."

"Good! Then let your uncle be summoned. I have found out the secret."

"A thimbleful of old cognac, signor?" asked Masters.

"Willingly, my friend, willingly. I see how wise you both were. I approve and thank you. You thought that I had followed the others into the shades, yet meant to restore me if you could without frightening Sir Walter. To go to sleep was unpardonable."

Abraham Masters and Henry descended with the good news, while the old man drank.

"I shall detain you half an hour or so," he said, when they all returned to him. "But I have no fear that anybody will want to fall asleep."

Sir Walter spoke.

"Thank Heaven, signor, thank Heaven! All is well with you?"

"All is absolutely well with me, but then I have slept refreshingly for some time. You, I fear, have not closed your eyes."

"Would you have any objection to Masters hearing what you may have to tell us? By so doing a true and ungarbled report will get out to Chadlands."

"My report will go out to the whole world, Sir Walter. All is accomplished and established on certain proofs. Your good spaniel has played his part also. I salute him--the old Prince."

Henry now observed that the dog was stretched on the floor at Signor Mannetti's feet.

"Still asleep?"

Mary knelt to pat the spaniel and started back.

"How horribly cold he is!"

"For ever asleep--a martyr to science. He was to die on Friday, remember. He has received euthanasia a little sooner, and nothing in his life has become him like the leaving of it. The last victim of the Grey Room. Mourn him not, he pa.s.sed without a pang--as did his betters."

"But, but--you spoke of crime and criminals!" gasped Sir Walter.

"And truly. Great crimes have been committed in this room and great criminals committed them. Is a crime any less a crime because the doers have mouldered in their dishonored graves for nearly five hundred years?"

"Your handling of speech is not ours, and you use words differently. The old dog did not suffer, you say? How did he come to die--in his sleep?"

"Even so. Without a sigh, the last venerable victim of this murdering shadow."

"You saw him die, and yet were safe yourself, sir?" asked Lennox.

"That is what happened. Now sit down all of you, father Abraham also, and in five minutes all will be as clear as day."

They obeyed him silently.

"Yes, a master criminal, one whose name has rung down the ages and will from to-morrow win a further resonance. Would that we could bring him to account; but he has already gone to it, if justice lies at the root of things, as all men pray, and you and I believe, Sir Walter. An interesting reflection: How many suffer, if they do not actually perish, from the sins of the dead? Not only the sins of our father are visited upon us, but, if we could trace the infliction, the crimes of countless dead men accomplished long before we were born into this suffering world. I speak in a parable, but this is literal, actual. Dead men committed these murders, and left this legacy of woe."

Signor Mannetti stroked the lifeless spaniel.

"When we were left alone I picked him up and set him on the bed. He did not waken, and I knew that he would never waken again. Now let us look at this n.o.ble bed, if you please. Here is the link, you see, without which so much that I told you yesterday must have sounded no more than the idle chatter of an old man. Come and use your eyes. Ah, if only people had used their eyes sooner!"
