"I have been indulging in the luxury of a retreat in a religious house," answered Giovanni with perfect truth.

Corona glanced at him and both laughed happily, as they had not laughed for many days and weeks. Saracinesca looked incredulously across the table at his son.

"You chose a singular moment for your devotional exercises," he said. "Where will piety hide herself next, I wonder? As long as Corona is satisfied, I am. It is her business."

"I am perfectly satisfied, I assure you," said Corona, whose black eyes were full of light. Giovanni raised his glass, looked at her and smiled lovingly. Then he emptied it to the last drop and set it down without a word.

"Some secret, I suppose," said the old gentleman gruffly.

CHAPTER XXVIII.

Arnoldo Meschini was not, perhaps, insane in the ordinary sense of the word; that is to say, he would probably have recovered the normal balance of his faculties if he could have been kept from narcotics and stimulants, and if he could have been relieved from the distracting fear of discovery which tormented him when he was not under the influence of one or the other. But the latter condition was impossible, and it was the extremity of his terror which almost forced him to keep his brain in a clouded state. People have been driven mad by sudden fright, and have gradually lost their intellect through the constant presence of a fear from which there is no escape. A man who is perpetually producing an unnatural state of his mind by swallowing doses of brandy and opium may not be insane in theory; in actual fact, he may be a dangerous madman. As one day followed another Meschini found it more and more impossible to exist without his two comforters. The least approach to lucidity made him almost frantic. He fancied every man a spy, every indifferent glance a look full of meaning. Before long the belief took possession of him that he was to be made the victim of some horrible private vengeance. San Giacinto was not the man, he thought, to be contented with sending him to the galleys for life. Few murderers were executed in those days, and it would be a small satisfaction to the Montevarchi to know that Arnoldo had merely been transferred from his study of the library catalogue to the breaking of stones with a chain gang at Civitavecchia. It was more likely that they would revenge themselves more effectually. His disordered imagination saw horrible visions. San Giacinto might lay a trap for him, might simply come at dead of night and take him from his room to some deep vault beneath the palace. What could he do against such a giant? He fancied himself before a secret tribunal in the midst of which towered San Giacinto's colossal figure. He could hear the deep voice he dreaded pronouncing his doom. He was to be torn to shreds piecemeal, burnt by a slow fire, flayed alive by those enormous hands. There was no conceivable horror of torture that did not suggest itself to him at such times. It is true that when he went to bed at night he was generally either so stupefied by opium or so intoxicated with strong drink that he forgot even to lock his door. But during the day he was seldom so far under the power of either as not to suffer from his own hideous imaginings. One day, as he dragged his slow pace along a narrow street near the fountain of Trevi, his eyes were arrested by an armourer's window. It suddenly struck him that he had no weapon of defence in case San Giacinto or his agents came upon him unawares. And yet a bullet well placed would make an end even of such a Hercules as the man he feared. He paused and looked anxiously up and down the street. It was a dark day and a fine rain was falling. There was nobody about who could recognise him, and he might not have another such opportunity of providing himself unobserved with what he wanted. He entered the shop and bought himself a revolver. The man showed him how to load it and sold him a box of cartridges. He dropped the firearm into one of the pockets of his coat, and smiled as he felt how comfortably it balanced the bottle he carried in the other. Then he slunk out of the shop and pursued his walk.

The idea of making capital out of the original deeds concerning the Saracinesca, which had presented itself to him soon after the murder, recurred frequently to his mind; but he felt that he was in no condition to elaborate it, and promised himself to attend to the matter when he was better. For he fancied that he was ill and that his state would soon begin to improve. To go to San Giacinto now was out of the question. It would have been easier for him to climb the cross on the summit of St. Peter's, with his shaken nerves and trembling limbs, than to face the man who inspired in him such untold dread. He could, of course, take the alternative which was open to him, and go to old Saracinesca. Indeed, there were moments when he could almost have screwed his courage to the point of making such an attempt, but his natural prudence made him draw back from an interview in which he must incur a desperate risk unless he had a perfect command of his faculties. To write what he had to say would be merely to give a weapon against himself, since he could not treat the matter by letter without acknowledging his share in the forgeries. The only way to accomplish his purpose would be to extract a solemn promise of secrecy from Saracinesca, together with a guarantee for his own safety, and to obtain these conditions would need all the diplomacy he possessed. Bad as he was, he had no experience of practical blackmailing, and he would be obliged to compose his speeches beforehand with scrupulous care, and with the wisest forethought. For the present, such work was beyond his power, but when he was half drunk he loved to look at the ancient parchments and build golden palaces in the future. When he was strong again, and calm, he would realise all his dreams, and that time, he felt sure, could not be far removed.

Nevertheless the days succeeded each other with appalling swiftness, and nothing was done. By imperceptible degrees his horror of San Giacinto began to invade his mind even when it was most deadened by drink. So long as an idea is new and has not really become a habit of the brain, brandy will drive it away, but the moment must inevitably come when the stimulant loses its power to obscure the memory of the thing dreaded. Opium will do it more effectually, but even that does not continue to act for ever. The time comes when the predominant thought of the waking hours reproduces itself during the artificial sleep with fearful force, so that the mind at last obtains no rest at all. That is the dangerous period, preceding the decay and total collapse of the intellect under what is commonly called the fixed idea. In certain conditions of mind, and notably with criminals who fear discovery, the effects of opium change very quickly; the downward steps through which it would take months for an ordinary individual to pass are descended with alarming rapidity, and the end is a thousand times more horrible. Meschini could not have taken the doses which a confirmed opium-eater swallows with indifference, but the result produced was far greater in proportion to the amount of the narcotic he consumed. Before the week which followed the deed was ended, he began to see visions when he was apparently awake. Shapeless, slimy things crawled about the floor of his room, upon his table, even upon the sheets of his bed. Dark shadows confronted him, and changed their outlines unexpectedly. Forms rose out of the earth at his feet and towered all at once to the top of the room, taking the appearance of San Giacinto and vanishing suddenly into the air. The things he saw came like instantaneous flashes from another and even more terrible world, disappearing at first so quickly as to make him believe them only the effects of the light and darkness, like the ghost he had seen in his coat. In the beginning there was scarcely anything alarming in them, but as he started whenever they came, he generally took them as a warning that he needed more brandy to keep him up. In the course of a day or two, however, these visions assumed more awful proportions, and he found it impossible to escape from them except in absolute stupor. It would have been clear to any one that this state of things could not last long. There was scarcely an hour in which he knew exactly what he was doing, and if his strange behaviour escaped observation this was due to his solitary way of living. He did not keep away from the palace during the whole day, from a vague idea that his absence might be thought suspicious. He spent a certain number of hours in the library, doing nothing, although he carefully spread out a number of books before him and dipped his pen into the ink from time to time, stupidly, mechanically, as though his fingers could not forget the habit so long familiar to them. His eyes,—which had formerly been unusually bright, had grown dull and almost bleared, though they glanced at times very quickly from one part of the room to another. That was when he saw strange things moving in the vast hall, between him and the bookcases. When they had disappeared, his glassy look returned, so that his eyeballs seemed merely to reflect the light, as inanimate objects do, without absorbing it, and conveying it to the seat of vision. His face grew daily more thin and ghastly. It was by force of custom that he stayed so long in the place where he had spent so much of his life. The intervals of semi-lucidity seemed terribly long, though they were in reality short enough, and the effort to engage his attention in work helped him to live through them. He had never gone down to the apartments where the family lived, since he had knelt before the catafalque on the day after the murder. Indeed, there was no reason why he should go there, and no one noticed his absence. He was a very insignificant person in the palace. As for any one coming to find him among the books, nothing seemed more improbable. The library was swept out in the early morning and no one entered it again during the twenty-four hours. He never went out into the corridor now, but left his coat upon a chair near him, when he remembered to bring it. As a sort of precautionary measure against fear, he locked the door which opened upon the passage when he came in the morning, unlocking it again when he went away in order that the servant who did the sweeping might be able to get in.

The Princess Montevarchi was still dangerously ill, and Faustina had not been willing to leave her. San Giacinto and Flavia were not living in the house, but they spent a good deal of time there, because San Giacinto had ideas of his own about duty, to which his wife was obliged to submit even if she did not like them. Faustina was neither nervous nor afraid of solitude, and was by no means in need of her sister's company, so that when the two were together their conversation was not always of the most affectionate kind. The consequence was that the young girl tried to be alone as much as possible when she was not at her mother's bedside. One day, having absolutely nothing to do, she grew desperate. It was very hard not to think of Anastase, when she was in the solitude of her own room, with no occupation to direct her mind. A week earlier she had been only too glad to have the opportunity of dreaming away the short afternoon undisturbed, letting her girlish thoughts wander among the rose gardens of the future with the image of the man she loved so dearly, and who was yet so far removed from her. Now she could not think of him without reflecting that her father's death had removed one very great obstacle to her marriage. She was by no means of a very devout or saintly character, but, on the other hand, she had a great deal of what is called heart, and to be heartless seemed to her almost worse than to be bad. In excuse of such very untheological doctrines it must be allowed that her ideas concerning wickedness in general were very limited indeed, if not altogether childish in their extreme simplicity. It is certain, however, that she would have thought it far less wrong to run away with Gouache in spite of her family than to entertain any thought which could place her father's tragic death in the light of a personal advantage. If she had nothing to do she could not help thinking of Anastase, and if she thought of him, she could not escape the conclusion that it would be far easier for her to marry him, now that the old prince was out of the way. It was therefore absolutely necessary to find some occupation.
