From Hell (1991)

The collected edition (first published in 1999) Alan Moore and Eddie Campbell's 572-page speculation on the identity and motives of Jack the Ripper, serialized from 1989 to 1998, and the slowest burn on this list in the best way. Campbell's scratchy ink makes Victorian London feel grimy and close, and Moore builds his theory of the murders with the patience of a historian. This is a book for the long middle of the flight, when you can give it full attention; skim it and the threads slip away. The violence is graphic. The scratchy art survives a tablet, though small text is easier in print.
