So don't ask me any questions when I call. It may be that something will go wrong, but I'll tell you if it does. I don't think it will. There will be nothing more to worry about, for Charles will be very, very safe. He is now—safer than you dream. You need hold no fears about Allen, and who or what he is. He forms as much a part of the past as Joseph Curwen's picture, and when I ring your doorbell you may feel certain that there is no such person. And what wrote that minuscule message will never trouble you or yours.
