There's nothing to be done. It's all
over. I can't tell you how I deplore this accident. If money can help
matters, I am willing to pay. The little girl ran right into my
automobile as I was turning the corner." Turning to the policeman, he
added: "It was an accident, officer, wasn't it? Thank God, you were a
witness to that. Everybody saw how it happened."

The policeman glared angrily at him. Almost savagely he replied:

"You may thank your stars it was, or you'd never have got out of this
neighborhood alive. They'd have strung you up to a lamppost sure as

The distracted mother, staring at the two men, had listened stupidly.
Suddenly she understood, and, pointing a scrawny finger at him, cried

One of the family?"

Tod did not like the man's cold, indifferent, almost brutal manner. It
was with an effort that he replied civilly:

"No--this lady was merely paying a visit here. The child was one of her
pupils. She is Miss Paula Marsh, teacher of the Rivington Street
Settlement."

The stranger started and looked at Paula more closely.

"The niece of Mr. James Marsh?" he cried, in surprise.

Tod nodded.

"Yes."

"How strange!" muttered the stranger. Drawing a card from his pocket, he
said: "I am Dr. Zacharie!"

Now Tod remembered where he had seen this man. It was through the
keyhole of the library the night of that secret midnight meeting.

Paula opened her eyes. At first she saw only Tod. Then her gaze,
wandering round the room suddenly rested on Dr. Za
