"You are a strange physician, sir," said Paul sternly. "You tell me that you are attending my mother, and yet you do not know what is the matter with her."

The doctor was not in the least offended by Paul's sharp answer. He smiled a little, but instantly became grave again, as he answered,—

"I am not a practicing physician. I am a specialist, and I devote my life to the study of mental complaints. Your mother is ill in mind, not in body."

"Mad!" exclaimed Paul, turning very pale. His life seemed to be nothing but a series of misfortunes.

"Certainly not hopelessly insane," replied Dr. Cutter, in a musing tone. "She has suffered a terrible shock, as you may imagine."

"Yes," said Paul, "of course. That is the reason why I have come all the way from Constantinople to see her. I could not go to my new post without telling her the whole story myself."

"Her manner is very strange," returned the other. "That is the reason why I waited for you here. I could not have allowed you to see her without being warned. She has a strange delusion, and you ought to know it."

"What is it?" asked Paul, in a thick voice.

"It is a very delicate matter. Come out into the garden, and I will tell you what I know."

The two men went out together, and walked slowly along the open path towards the woods. In the distance a few invalids moved painfully about the garden, or rested on the benches beneath the trees. Far off a party of children were playing and laughing merrily at their games.
