This exclamation seemed to imply some knowledge of the mystery; and it so impressed the auditors, among whom was Robert Hagburn, that they thought it not inexpedient to have an investigation; so the learned doctor was not uncivilly taken into custody and examined. Several interesting particulars, some of which throw a certain degree of light on our narrative, were discovered. For instance, that Sibyl Dacy, who was a niece of the doctor, had been beguiled from her home and led over the sea by Cyril Norton, and that the doctor, arriving in Boston with another regiment, had found her there, after her lover's death. Here there was some discrepancy or darkness in the doctor's narrative. He appeared to have consented to, or instigated (for it was not quite evident how far his concurrence had gone) this poor girl's scheme of going and brooding over her lover's grave, and living in close contiguity with the man who had slain him. The doctor had not much to say for himself on this point; but there was found reason to believe that he was acting in the interest of some English claimant of a great estate that was left without an apparent heir by the death of Cyril Norton, and there was even a suspicion that he, with his fantastic science and antiquated empiricism, had been at the bottom of the scheme of poisoning, which was so strangely intertwined with Septimius's notion, in which he went so nearly crazed, of a drink of immortality. It was observable, however, that the doctor--such a humbug in scientific matters, that he had perhaps bewildered himself--seemed to have a sort of faith in the efficacy of the recipe which had so strangely come to light, provided the true flower could be discovered; but that flower, according to Doctor Portsoaken, had not been seen on earth for many centuries, and was banished probably forever. The flower, or fungus, which Septimius had mistaken for it, was a sort of earthly or devilish counterpart of it, and was greatly in request among the old poisoners for its admirable uses in their art. In fine, no tangible evidence being found against the worthy doctor, he was permitted to depart, and disappeared from the neighborhood, to the scandal of many people, unhanged; leaving behind him few available effects beyond the web and empty skin of an enormous spider.
