"No," said Diana quickly, and came out into the sitting-room in her loose morning gown. "Where is he? Is he not in his room? He never comes into mine."

"He is not there," said the man, who by this time was thoroughly frightened. "He sent me for a lemonade. He looked better than usual, and was sitting just there, at his table, reading his letters. When I came back he was gone. He seemed entirely himself, better than I have ever seen him."

Diana was frightened and puzzled. After all it was quite possible that Marcantonio had taken it into his head to go out by himself. He had never suggested such a thing yet, and always seemed unwilling to cross the threshold alone; but since he was so much better that day, he might have gone out. It was possible. She would not have believed that without some immediate cause he could have fallen back into a remembrance of his troubles; for she had studied his moods very carefully, and was convinced that, as the doctor said, there would always be a blank in his mind now, destroying the memory of those three or four days. She glanced hastily over the papers on the table. They were all of the usual sort, for Marcantonio had taken Batiscombe's letter with him.

Nevertheless, she was very much frightened, and was angry with the confidential servant for not having sent some one else to get the lemonade. She lost no time in dispatching him to make inquiries. He was really an active man, and understood his business thoroughly, but Marcantonio's manner had completely deceived him, and he had conscientiously thought his charge perfectly safe. Maniacs have more than once deceived their keepers, and their doctors, and Marcantonio seemed to have fallen into a very different sort of madness—rather foolish and gentle than cunning and dangerous.

The servant soon discovered that Marcantonio had passed the porter's lodge and had taken a cab, not many minutes earlier; but no one had heard the order he gave to the driver. There were no more carriages on the stand. The man lost no time but ran down the street till he found one, and was driven to the station, as he was, bareheaded and clothed in a dress-coat and a white tie, after the manner of hotel servants in the morning. His experience told him that crazy people generally made for the railway when they escaped. But he was too late. A train had just left—he made anxious inquiries of every one, describing Marcantonio's clothes and jewelry, which he knew by heart. No one had noticed him. He might not have come to the station after all.

But a dirty little boy elbowed his way through the crowd of railway porters and guards that soon surrounded the man, and the boy listened.

"Had that signore a great ring on his finger, with a black stone in it, and a red one on each side?" he asked.

"Yes," cried the confidential servant. "You have seen him?" He seized the small boy by the arm and held him fast.

"Yes," said the little fellow; "but you have no need to pinch me like that. I sold him a paper, and he gave me a silver half-franc, and I noticed his fingers and his ring."

The servant released him.
