"And now good-by," the doctor said, grasping the young man's hand; "I know how I shall miss you, so I will cut short all leave-taking."

His voice was deep and low, as though he feared to betray how much he felt his friend's departure. Then he turned hastily away, and walked down the street with a rapid stride. Just as he reached his own door a dark figure emerged from the shadow where it had apparently been crouching, and said, timidly, "Ah, Herr Doctor."

"Is that you, Marianne?" he said, with a hasty glance at the woman. "What do you want? Is anything going wrong?"

"Ah, Herr Doctor, very, very wrong, I am afraid," she sighed. "He is out again, and indeed it would be better he should not come home, for he earned a trifle to-day, and he is spending it in drink, I suppose. If he should come home in one of his raging moods the lady will die----"

"Is she worse?" the doctor asked, hastily.

"Ah, good heavens! I don't know, but she talks so strange-like that I begged Christine, who lives just over me, to sit by her for a moment, and I ran all the way here to beg you to come to her if you can. She talked about you, and then prayed, and called herself wicked and ungrateful; it's hard to hear her talk so, when I know how good and gentle and unhappy she is, and how thankful she is for everything that is done for her. I thought to myself that the Herr Doctor would know just what to do, when you are so good as to pay my rent to the landlord to let me nurse the poor lady, and I came directly to you; and when they told me you were not at home I waited here until you should come, for---- But here we are already; indeed, doctor, you can run faster than I can."

Whilst Marianne had talked on they had reached the house where was lodged the patient whom the doctor had been called to visit at this late hour.

"Only wait one instant, Herr Doctor, till I light a candle," Marianne called out, when they had entered the passage-way. But before her match was lighted the doctor had groped his way up the narrow staircase and stood at the door of the sick-room.

The woman hastened after him, and both entered a low room but feebly illuminated by the light of a tallow candle.

A young girl, from her dress one of the working class, arose from the bedside where she had been sitting and came towards them.
