"Yes, human nature in its worst aspect selfishness, greed, unscrupulousness—and still human nature. Well, the woman followed him to New York and got some of the money, as Alora said; but the nurse wanted more, and was likely to bleed the man more liberally than he liked; so, being afraid of her, he ran away to Europe. Nurse spent her money, couldn't find Jason Jones to get more, and so returned to Chicago and practiced her profession again. Any dummy could figure that out."

"I cannot see," responded Mary Louise, "how that accounts for Alora's disappearance."

"Why, of course the woman knew all about the terms of the will. She was nursing a Mrs. Tolliver in this hotel when she discovered Alora's arrival. How she discovered it doesn't matter. In the morning, when the day nurse arrived to take her place, she left Mrs. Tolliver and went directly to Alora's room. The girl instantly recognized her and would probably have a warm place in her heart for her mother's old nurse. Decided to walk part of the way home with her so they could talk over old times—you and the Colonel being still asleep—but was enticed to the nurse's house and promptly locked up and held as a weapon to force old Jones to pay up. This completes the chain. A woman who would enter into such an ugly deal with Jason Jones as I have described would not hesitate to capture Alora, especially as it proved an easy thing to do."

Mary Louise drew a long breath. "If I could believe that theory, Josie," she said, "it would relieve me of much worry, for I'd know Alora is safe. But—what was it your father said about your imagination?"

Josie laughed. "This isn't wholly imagination, you goose, for it's based on a knowledge of human nature, as I've hinted. Also it's a scientific matching of the pieces in the puzzle. Why, Mary Louise, in this deduction we have all the necessary elements of the usual crime. A woman—always look for a woman in a mystery, my dear—money, the cause of four-fifths of all crimes, and a guilty man who is afraid of being forced to disgorge his ill-gotten gains. Then we will add an innocent girl who suffers through the machinations of others. Some of my conclusions may not be exactly correct, but in the main the story is absolutely logical."

"That's what you said last night, Josie, when you thought the governess, Gorham, had abducted Alora."

"True, but I have later information which doesn't entirely upset the theory but changes the actors in the drama. I don't say that further investigations may not alter this present plot in some of its details, but the main facts are too lucid and undeniable to get far away from. I'm now going to interview the house physician and get Mrs. Orme's address."

When she had gone, Mary Louise went to Gran'pa Jim with the tale of Josie's latest discoveries and Colonel Hathaway was so impressed by the theory that he decided to telegraph Peter Conant to catch the noon train and come straight to Chicago.

"The complications suggested by Josie will require a lawyer's advice," he said, "and Mr. Conant knows law and can advise us how to handle the case when we have discovered where Alora is confined."

Meanwhile Josie went to the doctor's office and after waiting some time, was finally admitted to his private room.
