As a Dorothy Sayers fan, I’m flat out horrified by this vintage cover art for Strong Poison
Unless I’m mistaken, it appears the seductive blonde in the painted-on dress is meant to be Harriet Vane. (Harriet was a paragon of intelligence, independence and wit, an Oxford graduate, and a most “decided-looking brunette.”)
If the artist had to vamp her into a pulp starlet, couldn’t he at least have let her keep her natural hair color? Grrrr.
