She burst into vehement tears.
"But you weep too soon," he protested. "I have saved you as usual from yourself, but only to inflict my own punishment. Don't weep those crocodile diamonds until you have heard your own sentence. Of course you know that I have followed every step you took in this matter. You are clever enough to have guessed that. You discovered all that was to be discovered, of course. But you are too keen. If this trial had come to pass you would have been on the witness stand, and the dogs would have caught the scent then never to lose it. You would have ruined your husband as well as yourself."
"Why do you let him talk to me so?" she screamed at Curran.
"Because it is for your good," Arthur answered. "But here's briefness. You must leave New York at once, and forever. Get as far from it as you can, and stay there while I am alive. And for consolation in your exile take your child with you, your little boy, whom Mrs. Endicott parades as her little son, the heir of her beloved Horace."
A frightful stillness fell in the room with this terrific declaration. But for pity he could have laughed at the paralysis which seized both the detective and his wife. Edith sat like a statue, white-faced, pouting at him, her hands clasped in her lap.
"Well, are you surprised? You, the clever one? If I am Horace Endicott, as you pretend to believe, do I not know the difference between my own child and another's? I am Arthur Dillon only, and yet I know how you conspired with Mrs. Endicott to provide her with an heir for the Endicott money. You did this in spite of your husband, who has never been able to control you, not even when you chose to commit so grave a crime. Now, it is absolutely necessary for the child's sake that you save him from Mrs. Endicott's neglect, when he is of no further use to her. She loves children, as you know."
"Who are you, anyway?" Curran burst out hoarsely after a while.
"Not half as good a detective as you are, but I happen in this matter to be on the inside," Arthur answered cheerfully. "I knew Horace Endicott much better than his wife or his friends. The poor fellow is dead and gone, and yet he left enough information behind him to trouble the clever people. Are you satisfied, Colette, that this time everything must be done as I have ordered?"
"You have proved yourself Horace Endicott," she gasped in her rage, burning with hate, mortification, shame, fifty tigerish feelings that could not find expression.
"Fie, fie, Colette! You have proved that I am Arthur Dillon. Why go back on your own work? If you had known Horace Endicott as I did, you would not compare the meek and civilized Dillon with the howling demon into which his wife turned him. That fellow would not have sat in your presence ten minutes knowing that you had palmed off your child as his, without taking your throat in his hands for a death squeeze. His wife would not have escaped death from the madman had he ever encountered her. Here are your orders now; it is late and I must not keep you from your beauty sleep; take the child as soon as the Endicott woman sends him to you, and leave New York one hundred miles behind you. If you are found in this city any time after the month of September, you take all the risks. I shall not stand between you and justice again. You are the most ungrateful sinner that I have ever dealt with. Now go and weep for yourself. Don't waste any tears on Mrs. Endicott."
