Odette Rider sat back in a corner of the smooth-running taxicab. Her eyes were closed, for the inevitable reaction had come. Excitement and anxiety had combined to give her the strength to walk to the cab with a firm step which had surprised the matron; but now, in the darkness and solitude, she was conscious of a depression, both physical and mental, which left her without the will or power for further effort.

The car sped through interminably long streets--in what direction she neither knew nor cared. Remember that she did not even know where the nursing home was situated. It might have been on the edge of London for all she was aware. Once, that was as the car was crossing Bond Street from Cavendish Square, she saw people turn and look at the cab and a policeman pointed and shouted something. She was too preoccupied to worry her head as to the cause.

She appreciated in a dim, vague way the skill of the taxi-driver, who seemed to be able to grope his way through and around any obstruction of traffic; and it was not until she found the cab traversing a country road that she had any suspicion that all was not well. Even then her doubts were allayed by her recognition of certain landmarks which told her she was on the Hertford Road.

"Of course," she thought. "I should be wanted at Hertford rather than in London," and she settled herself down again.

Suddenly the cab stopped, backed down a side lane, and turned in the direction from whence they had come. When he had got his car's head right, Sam Stay shut off his engine, descended from his seat, and opened the door.

She was on her knees, struggling to get to her feet, and she looked up at the little man wonderingly.

"I know you," she gasped. "You are the man who tried to get into my flat!"

He grinned.

"And I know you!" he laughed harshly. "You're the devil that lured him on! The best man in the world ... he's in the little vault in Highgate Cemetery. The door is just like a church. And that's where you'll be to-night, damn you! Down there I'm going to take you. Down, down, down, and leave you with him, because he wanted you!"

He was gripping her by both wrists, glaring down into her face, and there was something so wolfish, so inhuman, in the madman's staring eyes that her mouth went dry, and when she tried to scream no sound came. Then she lurched forward towards him, and he caught her under the arms and dragged her to her feet.

"Fainted, eh? You'll faint, me lady," he chuckled. "Don't you wish you might never come round, eh? I'll bet you would if you knew ... if you kn............
