Oil! by Upton Sinclair

Bertie arrived in Angel City a week behind her brother, and afforded him still more evidence of the unchangeable nature of femininity. Bertie had come to get her share of the estate, and she went after it with the single-mindedness of a rabbit-hound. Bertie knew a lawyer -- her kind of lawyer, another rabbit-hound -- and she saw him the day of her arrival; and then Bunny must come to this lawyer's office, and with the help of Bertie and a stenographer have the insides of his mind turned out and recorded: exactly what Dad had said about his arrangements with Mrs. Alyse Huntington Forsythe Olivier -- Dad hadn't said a word about it to Bertie, alas, nor to anyone else; he had made a will, of course, and that infamous woman had destroyed it -- Bertie knew that with the certainty of God.

And then, everything else about Dad's affairs that Bunny could recall; where he had kept his money and his papers, what secret hiding-place for stocks and bonds he may have had, what he had spent, so far as Bunny could guess, who had been in his confidence. And then the statements which Vernon Roscoe rendered; and all the files of Dad's correspondence with Verne; and the trusted young executives -- Bolling and Heimann and Simmons and the rest; and the bankers and their clerks; and Dad's secretary whom Bertie had brought back from Paris with her -- a veritable mountain of detail, and Bunny was required to attend all the sessions, and be just as much a rabbit-hound as the rest. He told himself that it was his duty to the movement, which so badly needed the aid of a "fat angel"!
