Until then I also saw nothing but madness in the wild tales I have acted on. Even now I ask myself whether I was misled—or whether I am not mad after all. I do not know—but others have strange things to tell of Edward and Asenath Derby, and even the stolid police are at their wits' ends to account for that last terrible visit. They have tried weakly to concoct a theory of a ghastly jest or warning by discharged servants; yet they know in their hearts that the truth is something infinitely more terrible and incredible.
