"Old King Brady, your life is in danger."

"From what?"

"The man you are persecuting."

"You mean Paul La Croix, I presume?"

"I do. Go back to New York at once."

"Madam, I shall do nothing of the kind."

"Then you must suffer for your obstinacy."

"I am prepared for anything, madam."

"Remember, I have given you fair warning. You cannot arrest La Croix on
Canadian soil for smuggling."

And the veiled woman in deep mourning, who accosted the old detective in a
dark street in Toronto, turned as if to walk away.

This happened several weeks after the Bradys reached Buffalo.

They had been vainly searching for La Croix and his wife.

On the night in question, Old King Brady had gone out from his hotel alone,
when the woman in mourning met him in the street.
