"Naturally, at his age. But I think we are going to pull him through."

Derry went into the shadowed room. His father was breathing heavily. Something clutched at the boy's heart—the fear of the Thing which lurked in the darkness—a chill and sinister figure with a skeleton hand.

He could not have his father die. He would feel as if his thoughts had killed him—a murderer in intention if not in deed. Not thus must the Obstacle be removed. He raised haggard eyes to the Doctor's face. "You—you mustn't think that I store things up against him. He's all I have."

The Doctor's keen glance appraised him. "Don't get morbid over it; he has everything in his favor—and Miss Merritt is famous in such cases."

Hilda took his praise with downcast eyes. Her manner with the Doctor when others were present was professionally deferential. It was only when they were alone that the nurse was submerged in the woman.

With her bonnet off and a white cap in its place, she moved about the room. "I shall be very comfortable," she said, when Derry inquired if anything could be done for her.

"We haven't any women about the place but Cook," he explained. "She has been in our family forever—"

"I'll put a day nurse on tomorrow," the Doctor said, "but I want Hilda with him at night; she can call me up if there's any change, and I'll come right over."

When the Doctor had gone, Derry, seeking his room, found Muffin waiting. Bronson bustled in to see that his young master got out of his wet clothes and into a hot bath. "All the time the Doctor was talking to you, I was worrying about your shoes. Your feet are soaked, sir. Whatever made you walk in the rain?"

"I couldn't ride—I couldn't."
