notGuilty :: [Boy]
notGuilty = [x | x <- boys, length ( accusers x) /= 3]

Shorter

notGuilty :: [Boy]
notGuilty =  boys \\ guilty

A good remark!

-- A boy made a honest statement if he accused the guilty boys and didn't acused the non-guilty boys
honest :: [Boy]
honest = nub [x | x <- boys, y <- guilty, z <- notGuilty, accuses x y && not (accuses x z)]

Well done!
