One Perfect Moment: FROM HELL--Sir William Gull
The Essence of FROM HELL's William Withey Gull.
Which is to be distinguished from the actual Gull, as Moore and Campbell make no claim he is Jack the Ripper, just that he worked well for the story. That in mind, here's six pages(well under the 1/3 limit--it's a 38-page chapter from a looong book)from Chapter 4, which some readers might skip over as it's basically, on the face of it, a tour of churches and obelisks in London, without any action or, apparently, intrigue. But in fact this chapter may be the most important one, and carries the essence of Gull in it. This first page below in particular is interesting because it features the line that led Moore to become a magician. See if you can guess it.
And here's a moment that chills my spine to this day. Particularly Gull's smile.
