“That will do, Gurther.” Oberzohn’s voice was sharp. He, too, had interpreted the stare. “You need not wait.”

Gurther obediently stalked from the room, and the doctor followed. Almost before the trap had fastened down she was by the girl’s side, with a basin of water and a wet towel. The second the water touched her face, Joan opened her eyes and gazed wildly up at the vaulted ceiling, then rolling over from the bed to her knees, she struggled to her feet, swayed and would have fallen, had not Mirabelle steadied her.

“They’ve got him! They’ve got my boy . . . killed him like a dog!”

“What—Mr.—Mr. Newton?” gasped Mirabelle, horrified.

“Killed him—Monty—Monty!”

And then she began to scream and run up and down the room like a thing demented. Mirabelle, sick at heart, almost physically sick at the sight, caught her and tried to calm her, but she was distracted, half mad. The drug and its antidote seemed to have combined to take away the last vestige of restraint. It was not until she fell, exhausted, that Mirabelle was able to drag her again to the bed and lay her upon it.

Montague Newton was dead! Who had killed him? Who were the “they”? Then she thought of Gurther in his strange attire; white dress-front crumpled, even his beard disarranged in the struggle he had had with the overwrought woman.

In sheer desperation she ran up the steps and tried the trap, but it was fast. She must get away from here—must get away at once. Joan was moaning pitiably, and the girl sat by her side, striving to calm her. She seemed to have passed into a state of semi-consciousness; except for her sobs, she made no sound and uttered no intelligible word. Half an hour passed—the longest and most dreadful half-hour in Mirabelle Leicester’s life. And then she heard a sound. It had penetrated even to the brain of this half-mad girl, for she opened her eyes wide, and, gripping Mirabelle, drew herself up.

“He’s coming,” she said, white to the lips, “coming . . . the Killer is coming!”

“For God’s sake don’t talk like that!” said Mirabelle, beside herself with fear.
