She was mistaken, however, as any indifferent person would have seen in a moment. He was insane, and on the verge of becoming violent. Nothing but her wonderful courage and strong will had kept him within any bounds, and he might at any moment become wholly uncontrollable.
She would have stopped in Florence if it had been possible, but it seemed dangerous to thwart him at present, and she felt sure that in Turin she could get the help of some first-rate physician. So she submitted once more, and in an hour they were off again, in a reserved carriage, as before, flying northwards towards the mountains, where the road winds so wonderfully through a hundred tunnels, in its rapid ascent.
It was a very long night for Diana. In all her many journeys she had never felt fatigue such as this. Marcantonio would sleep for an hour, and then start up suddenly and begin to talk, sometimes asking questions and sometimes volunteering remarks that showed how his mind was wandering. Once or twice he showed signs of returning to the account of his doings after Leonora had left him, but Diana was able to check him in time, for he was growing tired and yielded more easily to her will than in the daytime.
At last they were safe in the hotel, and Marcantonio was in his room, intending to dress, he said, before going out. Diana was no sooner assured that she was free from the responsibility of watching him for a few minutes than she sent for the proprietor of the hotel, inquired for the address of the best physician in Turin, and dispatched a messenger with a very urgent request for his attendance.
The apartment she had taken with her brother consisted of a large sitting-room, with a bedroom on each side of it. Marcantonio's room had but that one door, which she could watch as she lay on the sofa, awaiting the arrival of the doctor.
When he came at last, breathless in his haste to put himself at the service of the great lady who sent for him, he talked very learnedly for half an hour, after listening to all Diana told him with grave attention. He could not see the patient of course, and the interview took place in a small antechamber, from which he could escape if Marcantonio were heard moving within. He was of opinion that it was not a case of insanity, but of temporary derangement of the faculties from the severe strain they had received. The sudden manifestations of violence were natural enough to an Italian,--if it had been the case of an Englishman, it would have been different, because, as the doctor said, half in earnest and half in jest, Inglesi were generally mad to begin with, and anything beyond that made them furious maniacs. He had a man, he said, long accustomed to dealing with lunatics. He would send him disguised as a servant, and he could be in constant attendance, thus relieving Diana of the care of watching the marchese. He himself would call every day and inquire, and would be ready at a moment's notice to remove him to a place of safety. In his present state, he said, to shut him up, and treat him as though he were insane, might very likely make a permanent madman of him.
