Book excerpt: A Matter of Millions by Anna Katharine Green is a classic thriller mystery from the 1800s in which a dying old woman leaves her entire inheritance to a stranger. Excerpt: "An old crone stood on the top floor of one of New York's studio buildings. In her hand was a letter. Looking at it, she studied the superscription carefully, and then, with the same intentness, read the name on one of the doors before her. Hamilton Degraw was on the one, Hamilton Degraw was on the other."
