Kalmon, leaning back inside, had not heard the sound of the latch, and paid no attention to Nino's growl. It was natural that such an animal should growl and snarl for nothing, he thought, especially on a rainy night, when the lamps of a cab throw strange patches of light on the glistening pavement.
There was some reason why Ercole, who had heard, did not get down and tell the Professor, who had noticed nothing. One reason, and a good enough one, was that whoever it was that had opened the door so cautiously, it certainly was not the man they were all hunting that night. Yet since Ercole knew the little house, and probably knew who lived there, and that it belonged to Marcello, it might have been supposed that he would have told the latter, whose footsteps were heard on the gravel a few moments afterwards. But though Marcello stood a moment by the wheel close to Ercole, and spoke across him to the cabman, Ercole said nothing. Nino had not growled at Marcello, even before the latter had appeared, for Nino had a good memory, for a dog, and doubtless remembered long days spent by the Roman shore, and copious leavings thrown to him from luxurious luncheons. Before they had left the villa he had sniffed at Marcello's clothes and hands in a manner that was meant to be uncommonly friendly, though it might not have seemed reassuring to a stranger; and Marcello had patted his huge head, and called him by name.
The young man had given the cabman the address of the office of the Chief of Police, and when he had got in and hooked up the leathern apron, the cab rolled away over the stones through the dark streets, towards the bridge of Saint Bartholomew.
Within the house Regina sat alone, as Marcello had found her, her chin resting on the back of her closed hand, her elbow on her knee, her eyes gazing at the bright little fire that blazed on the polished hearth. Her hair was knotted for the night, low down on her neck, and the loose dressing-gown of dove-coloured silk plush was unfastened at the neck, where a little lace fell about her strong white throat.
She had sprung to her feet in happy surprise when Marcello had entered the room, though it was not two hours since he had left her, and she could still smell the smoke of his last cigarette. She had felt a sudden chill when she had seen his face, for she never saw him look grave and preoccupied without believing that he had grown suddenly tired of her, and that the end had come. But then she had seen his eyes lighten for her, and she had known that he was not tired of her, but only very much in earnest and very much in a hurry.
He had bidden her find out from Settimia where Corbario was, if the woman knew it; he had told her to find out at any cost, and had put a great deal of emphasis on the last words. In answer to the one question she asked, he told her that Corbario was a murderer, and was trying to escape. He had not time to explain more fully, but he knew that he could count on her. She did not love Folco Corbario, and she came of a race that could hate, for it was the race of the Roman hill peasants. So he left her quickly and went on.
But when he was gone, Regina sat quite still for some time, looking at the fire. Settimia was safe in her own room, and was probably asleep. It would be soon enough to wake her when Regina had considered what she should say in order to get the information Marcello wanted. Settimia would deny having had any communication with Corbario, or that she knew anything of his whereabouts. The next step would probably be to tempt her with money or other presents. If this failed, what was to be done? Somehow Regina guessed that a bribe would not have much effect on the woman.
Marcello had wished to send her away long ago, but Regina had persuaded him to let her stay. It was part of her hatred of Corbario to accumulate proofs against him, and they were not lacking in the letters he wrote to Settimia. Regina could not understand the relation in which they stood to each other, but now and then she had found passages in the letters which referred neither to herself nor Marcello, but to things that had happened a good many years ago in another country. She was convinced that the two had once been companions in some nefarious business, of which they had escaped the consequences. It was her intention to find out exactly what the deed had been, and then to bring Corbario to ruin by exposing it. It was a simple scheme, but it seemed a sure one, and Regina was very patient. Corbario had tried to separate her from Marcello, and she had sworn that he should pay her for that; and besides, he had wished to kill Marcello in order to get his money. That was bad, undoubtedly—very bad; but to her peasant mind it was not unnatural. She had heard all her life of crimes committed for the sake of an inheritance; and so have most of us, and in countries that fondly believe themselves much more civilised than Italy. That was extremely wicked, but the attempt had failed, and it sank into insignificance in comparison with the heinous crime of trying to separate two lovers by treachery. That was what Regina would not forgive Corbario.
Nor would she pardon Settimia, who had been Corbario's instrument and helper; and as she meant to include the woman in her vengeance, she would not let her go, but kept her, and treated her so generously and unsuspiciously that Settimia was glad to stay, since Corbario still wished it.
Regina looked at the little travelling-clock that stood on the low table at her elbow, and saw that it was half-past eleven. Behind the drawn curtains she could hear the rain beating furiously against the shutters, but all was quiet within the house. Regina listened, for Settimia's room was overhead, and when she moved about her footsteps could be heard in the sitting-room. Regina had heard her just before Marcello had come in, but there was no sound now; she had probably gone to bed. Regina lit a candle and went into her own room.
