Arthur Conan Doyle
389 cryptograms in the catalog, every one taken from Arthur Conan Doyle’s own writing rather than from a quotation list.
The Sherlock Holmes stories and The Hound of the Baskervilles. Holmes explains himself constantly, and that is the form, so his lines arrive pre-shaped as statements about method, which is a genre of quotation almost nobody else here produces.

How hard they are
Graded by the model in our guide to solving cryptograms: 100 easy, 164 medium and 125 hard. Most of Arthur Conan Doyle’s puzzles land in the medium tier.
They average 71.1 letters over 19.2 distinct ones, with 4.2 letters appearing exactly once, which are the letters a frequency count cannot help you with. 9.8% carry an apostrophe, which hands over a letter outright.
