It was only about this time, Willett points out with much acuteness, that the nightmare qualities became indubitably linked with Ward, and the doctor feels shudderingly sure that enough solid evidence exists to sustain the youth's claim regarding his crucial discovery. In the first place, two workmen of high intelligence saw Joseph Curwen's ancient papers found. Secondly, the boy once showed him those papers and a page of the Curwen diary, and each of the documents had every appearance of genuineness. The hole where Ward claimed to have found them is a visible reality, and Willett had a very convincing final glimpse of them in surroundings which can scarcely be believed and can never perhaps be proved. Then there were the mysteries and coincidences of the Orne and Hutchinson letters, and the problem of the Curwen penmanship and of what the detectives brought to light about Dr. Allen; these things, and the terrible message in mediaeval minuscules found in Willett's pocket when he gained consciousness after his shocking experience.
