For answer, the lawyer put his fingers to his lips with a warning gesture, and beckoning the young man to follow, retraced his steps on tiptoe along the narrow, dark hall and down the filthy, winding staircase. Not a word was spoken by either man until they reached the street. Once in the open air, the lawyer turned and said:

"Dick, we've uncovered as black a plot as was ever hatched in hell. If we don't queer the game and put them all in the chair it won't be my fault. We can't bring poor Kenneth back to life, but we can and will revenge his cowardly murder. It will be a positive joy to me to see that arch-scoundrel Keralio electrocuted."

"What do you propose to do?" asked his companion. "Hadn't we better call Mrs. Traynor on the telephone and warn her before it's too late?"

The lawyer was silent for a few moments. Then meditatively, he said:

"No, that would be a mistake. No doubt, by this time, she has received Keralio's anonymous letter. She is probably frantic with anxiety over the news of her child's disappearance, and will respond eagerly to any clue that promises to take her to her child. If we warned her she would pay no heed. She might pretend to, but only to pacify us. Afraid that punishment might be visited on the child, she would obey the warning not to talk, and she will come here to Keralio's flat to-morrow at the time the letter stated. Of course, she has no idea Keralio wrote the letter. But even if she had, it would make no difference. I know her. She would run any risk to save her child."

"I think you're right," replied Dick, "but how, then, will you help her? There is no knowing what Keralio's object is in enticing her here—you can be sure it's nothing good."

"Precisely—that's why we, too, must be on hand, together with a strong force of detectives. We'll get them all. There will be no possible escape. We'll surround the house with men. They'll be caught like rats in a trap."

The lawyer turned to go.

"Where are you bound now?" asked Dick.

"To police headquarters!"
