When Dr. Herbert West disappeared a year ago, the Boston police questioned me closely. They suspected that I was holding something back, and perhaps suspected graver things; but I could not tell them the truth because they would not have believed it. They knew, indeed, that West had been connected with activities beyond the credence of ordinary men; for his hideous experiments in the reanimation of dead bodies had long been too extensive to admit of perfect secrecy; but the final soul-shattering catastrophe held elements of daemoniac phantasy which make even me doubt the reality of what I saw.
