Robert Louis Stevenson

255 cryptograms in the catalog, every one taken from Robert Louis Stevenson’s own writing rather than from a quotation list.

Treasure Island and Kidnapped, both adventure novels narrated by a young man remembering. Stevenson keeps his sentences short and concrete. That makes his puzzles read plainly once they open, and gives the solver a challenge while they are still closed.
