"Nevertheless, the a.s.sa.s.sin was quite equal to smudging out the detectives, believe me, Sir Walter."

The day was fine, and Signor Mannetti expressed a wish to take the air.

They walked on the terrace presently, and Mary joined them. He asked for her arm, and she gave it.

Prince padded beside her, and the visitor declared interest in him.

"Like myself, your dog is on the verge of better things," he said. "He will do good deeds in the happy hunting grounds, be sure."

They told him the feats of Prince, and he appeared to be interested.

"Nevertheless, the faithful creature ought to die now. He is blind and paralysis is crippling his hinder parts."

Sir Walter patted the head of his ancient favorite.

"He dies on Friday," he said. "The vet will come then. I a.s.sure you the thought gives me very genuine pain."

"He has earned euthanasia, surely. What is that fine tree with great white flowers? I have seen the like before, but am sadly ignorant of horticulture."

"A tulip-tree," said Mary. "It's supposed to be the finest in Devonshire."

"A beautiful object. But all is beautiful here. An English spring can be divine. I shall ask you to drive me to primroses presently. Those are azaleas--that bank of living fire--superb!"

He praised the scene, and spoke about the formal gardens of Italy.

Then, when luncheon was finished and he had smoked a couple of cigarettes, Signor Mannetti rose, bowed to Sir Walter, and said:

"Now, if you please."

They accompanied and watched him silently, while his eyes wandered round the Grey Room.

The place was unchanged, and the dancing cherubs on the great chairs seemed to welcome daylight after their long darkness.

The visitor wandered slowly from end to end of the chamber, nodded to himself, and became animated. Then he checked his gathering excitement, and presently spoke.

"I think I am going to help you, Sir Walter," he said.

"That is great and good news, signor."

Then the old man became inconsequent, and turned from the room to the contents. If, indeed, he had found a clue, he appeared in no haste to pursue it. He entered now upon a disquisition concerning the furniture, and they listened patiently, for he had showed that any interruption troubled him. But it seemed that he enjoyed putting a strain upon their impatience.

"Beautiful pieces," he said, "but not Spanish, as you led me to suppose.

Spanish chestnut wood, but nothing else Spanish about them. They are of the Italian Renaissance, and it is most seemly that Italian craftsmanship of such high order should repose here, under an Italian ceiling. Strange to say, my sleeping apartment at Rome closely resembles this room. I live in a villa that dates from the fifteenth century, and belonged to the Colonna. My chests are more superb than these; but your suite--the bed and chairs--I confess are better than mine. There is, however, a reason for that. Let us examine them for the sake of Mrs.

May. Are these carved chairs, with their reliefs of dancing putti, familiar to her--the figures, I mean?"

Mary shook her head.

"Then it is certain that in your Italian wanderings you did not go to Prato. These groups of children dancing and blowing horns are very cleverly copied from Donatello's famous pulpit in the duomo. The design is carried on from the chairs to the footboard of the bed; but in their midst upon the footboard is let in this oval, easel-picture, painted on wood. It is faded, and the garlands have withered in so many hundred years, as well they might; but I can feel the dead color quite well, and I also know who painted it."

"Is it possible, signor--this faint ghost of a picture?"

"There exists no doubt at all. You see a little Pinturicchio. Note the gay bands of variegated patterns, the arabesques and fruits. Their hues have vanished, but their forms and certain mannerisms of the master are unmistakable. These dainty decorations were the sign manual of such quattrocento painters as Gozzoli and Pinturicchio; and to these men he, for whom these works of art were created, a.s.signed the painting and adornment of the Vatican. We will come to him directly. It was for Michelangelo to make the creations of these artists mere colored bubbles and froth, when seen against the immensity and intellectual grandeur of his future masterpieces in the Sistine. But that was afterwards. We are concerned with the Pope for whom these chairs and this bed were made.

Yes, a Pope, my friends--no less a personage than Alexander VI.!"

He waited, like a skilled actor, for the tremendous sensation he expected and deserved. But it did not come. Unhappily for Signor Mannetti's great moment, his words conveyed no particular impression to anybody.

Sir Walter asked politely:

"And was he a good, or a bad Pope? I fear many of those gentlemen had little to their credit."

But the signor felt the failure of his great climax. At first he regretted it, and a wave of annoyance, even contempt, pa.s.sed unseen through his mind; then he was glad that the secret should be hidden for another four-and-twenty hours, to gain immensely in dramatic sensation by delay. Already he was planning the future, and designing wonderful histrionics. He could not be positive that he was right; though now the old man felt very little doubt.

He did not answer Sir Walter's question, but asked one himself.

"The detectives examined this apartment with meticulous care, you say?"

"They did indeed."

"And yet what can care and zeal do; what can the most conscientious student achieve if his activities are confounded by ignorance? The amazing thing to me is that n.o.body should have had the necessary information to lead them at least in the right direction. And yet I run on too fast. After all, who shall be blamed, for it is, of course, the Grey Room and nothing but the Grey Room we are concerned with. Am I right? The Grey Room has the evil fame?"

"Certainly it has."

"And yet a little knowledge of a few peculiar facts--a pinch of history--yet, once again, who shall be blamed? Who can be fairly asked to possess that pinch of history which means so much in this room?"

"How could history have helped us, signor?" asked Henry Lennox.

"I shall tell you. But history is always helpful. There is history everywhere around us--not only here, but in every other department of this n.o.ble house. Take these chairs. By the accident of training, I read in them a whole chapter of the beginnings of the Renaissance; to you they are only old furniture. You thought them Spanish because they were bought in Spain--at Valencia, as a matter of fact. You did not know that, Sir Walter; but your grandfather purchased them there--to the despair and envy of another collector. Yes, these chairs have speaking faces to me, just as the ceiling over them has a speaking face also.

It, too, is copied. History, in fact, breathes its very essence in this home. If I knew more history than I do, then other beautiful things would talk to me as freely as these chairs--and as freely as the trophies of the chase and the tiger skins below no doubt talk to Sir Walter. But are we not all historical--men, women, even children? To exist is to take your place in history, though, as in my case, the fact will not be recorded save in the 'Chronicles' of the everlasting. Yes, I am ancient history now, and go far back, before Italy was a united kingdom. Much entertaining information will be lost for ever when I die.

Believe me, while the new generation is crying forth the new knowledge and glorying in its genius, we of the old guard are sinking into our graves and taking the old knowledge with us. Yet they only rediscover for themselves what we know. Human life is the snake with its tail in its mouth--Nietzsche's eternal recurrence and the commonplaces of our forefathers are echoed on the lips of our children as great discoveries."

Henry Lennox ventured to bring him back to the point.

"What knowledge--what particular branch of information should a man possess, signor, to find out what you have found?"

"Merely an adornment, my young friend, a side branch of withered learning, not cultivated, I fear, by your Scotland Yard. Yet I have known country gentlemen to be skilled in it. The practice of heraldry.

I marked your arms on your Italian gates. I must look at those gates again--they are not very good, I fear. But the arms--a chevron between three lions--a fine coat, yet probably not so ancient as the gates."

"It was such a thing as bothered me in Florence," said Sir Walter. "I'd seen it before somewhere, but where I know not--a bull's head of gold on a red field."

Signor Mannetti started and laughed.

"Ha-ha! We will come to the golden bull presently, Sir Walter. You shall meet him, I promise you!"

Then he broke off and patted his forehead.

"But I go too quickly--far too quickly indeed. I must rest my poor brain now, or it will rattle in my head like a dry walnut. When it begins to rattle, I know that I have done enough for the present. May I walk in the garden again--not alone, but with your companionship?"

"Of course, unless you would like to retire and rest for a while."

"Presently I shall do so. And please permit n.o.body to enter the Grey Room but myself. Not a soul must go or come without me."
