The Illustrated Complete Works of H.P. Lovecraft

obtained secretly and at great cost—as many days as our vigils might need to be protracted. It was our design to sit up together till very late, and then watch singly till dawn in two-hour stretches, myself first and then my companion; the inactive member resting on the cot.
    The natural leadership with which my uncle procured the instruments from the laboratories of Brown University and the Cranston Street Armoury, and instinctively assumed direction of our venture, was a marvellous commentary on the potential vitality and resilience of a man of eighty-one. Elihu Whipple had lived according to the hygienic laws he had preached as a physician, and but for what happened later would be here in full vigour today. Only two persons suspect what did happen—Carrington Harris and myself. I had to tell Harris because he owned the house and deserved to know what had gone out of it. Then too, we had spoken to him in advance of our quest; and I felt after my uncle’s going that he would understand and assist me in some vitally necessary public explanations. He turned very pale, but agreed to help me, and decided that it would now be safe to rent the house.
    To declare that we were not nervous on that rainy night of watching would be an exaggeration both gross and ridiculous. We were not, as I have said, in any sense childishly superstitious, but scientific study and reflection had taught us that the known universe of three dimensions embraces the merest fraction of the whole cosmos of substance and energy. In this case an overwhelming preponderance of evidence from numerous authentic sources pointed to the tenacious existence of certain forces of great power and, so far as the human point of view is concerned, exceptional malignancy. To say that we actually believed in vampires or werewolves would be a carelessly inclusive statement. Rather must it be said that we were not prepared to deny the possibility of certain unfamiliar and unclassified modifications of vital force and attenuated matter; existing very infrequently in three-dimensional space because of its more intimate connexion with other spatial units, yet close enough to the boundary of our own to furnish us occasional manifestations which we, for lack of a proper vantage-point, may never hope to understand.
    In short, it seemed to my uncle and me that an incontrovertible array of facts pointed to some lingering influence in the shunned house; traceable to one or another of the ill-favoured French settlers of two centuries before, and still operative through rare and unknown laws of atomic and electronic motion. That the family of Roulet had possessed an abnormal affinity for outer circles of entity—dark spheres which for normal folk hold only repulsion and terror—their recorded history seemed to prove. Had not, then, the riots of those bygone seventeen-thirties set moving certain kinetic patterns in the morbid brain of one or more of them—notably the sinister Paul Roulet—which obscurely survived the bodies murdered and buried by the mob, and continued to function in some multiple-dimensioned space along the original lines of force determined by a frantic hatred of the encroaching community?
    Such a thing was surely not a physical or biochemical impossibility in the light of a newer science which includes the theories of relativity and intra-atomic action. One might easily imagine an alien nucleus of substance or energy, formless or otherwise, kept alive by imperceptible or immaterial subtractions from the life-force or bodily tissues and fluids of other and more palpably living things into which it penetrates and with whose fabric it sometimes completely merges itself. It might be actively hostile, or it might be dictated merely by blind motives of self-preservation. In any case such a monster must of necessity be in our scheme of things an anomaly and an intruder, whose extirpation forms a primary duty with every man not an enemy to the world’s life, health, and sanity.
    What baffled us was our utter ignorance of the aspect in which we might encounter the thing. No sane person had even seen it, and few had ever felt it definitely. It might be pure energy—a form ethereal and outside the realm of substance—or it might be partly material; some unknown and equivocal mass of plasticity, capable of changing at will to nebulous approximations of the solid, liquid, gaseous, or tenuously unparticled states. The anthropomorphic patch of mould on the floor,
