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.

The doctor retired, leaving Diana somewhat reassured. All that he had said seemed reasonable, and she would strictly follow his advice. Meanwhile, she went to her own room, feeling sure that she could hear Marcantonio's door open, if he finished dressing and came out. But Marcantonio rang his bell at the end of an hour, and sent word to his sister that he felt tired and had gone to bed, and would not rise till midday.

Poor fellow—she was pleased at the intelligence, but the fact was that his mind had strayed again; he had forgotten the object of his journey, and being worn out had gone to bed like a tired child. The new place, the strange room, and the necessity of unpacking his clothes himself had confused him, and driven everything else out of his head.

Before he awoke, the confidential man had arrived, arrayed in the ordinary dress of an hotel servant. He was a quiet individual, with strong hands and iron-grey hair, neat in his appearance, and a little hesitating in his speech; but his eyes were keen and searching, and he moved quickly. Diana was pleased with him, and understood that the doctor had given her good advice, and that Marcantonio would be safely watched. The man said he would serve them in their own sitting-room, and perform the offices of valet for Marcantonio, and be altogether in the position of a private servant, which, however, was not his profession, as he took care to add.

When at last Diana and Marcantonio met, each rested and refreshed, he looked the less weary of the two. Diana had suffered too much to be entirely herself, and for the first time in her life felt as though she had taxed her strength too severely. Moreover, the strain was not removed, but increased hourly. Her woman's instinct told her that, in spite of the doctor's opinion, her brother was actually out of his mind, perhaps past all recovery. His sudden cheerfulness was horrible to her, and made her shudder when she thought of the magnitude of what he was forgetting.

"Let us take a carriage and see Turin, Diana," he suggested gayly, as they finished their lunch and he lit a cigarette. "I have never been in Turin with you. There are some very pretty things to see."

"By all means," said she readily. "Let us go at once."

The confidential servant was dispatched for a carriage. The idea of seeing sights with his sister pleased Marcantonio, and he never relapsed into his sadder self during the afternoon. Diana did not know whether to be glad or sorry; his forgetfulness was terrible, but his memory was worse. She remembered the scene with the cross on the previous day, in the railway-carriage, and she thought that if insanity brought peace it was better to be insane.
