Take the following as truth: There was no one I could appeal to for help without giving myself away to THEM, and if I risked it and failed and Mrs. Vandemeyer looked so rich, and so beautifully dressed, that I felt convinced they'd take her word against mine, and think it was part of my mental trouble to think myself 'persecuted' I felt that the horrors in store for me would be too awful once they knew I'd been only shamming." Sir James nodded comprehendingly.
Then the following statement: ""I was sure that they would believe Mrs. Vandemeyer over me on account of her appearance."" is true, false, or inconclusive?
