I adore Heyer (and yeah, according to the curator of costume who turned me on to her, Heyer's research was a tad on the fanatical side, down to attempting to really work out which inn you could reach leaving London in a certain type of carriage with a certain number of horses) but...yeah. There are certain moments where her kind of blind kneejerkery came right through. I mean, at least Sayers, with all her issues, generally managed to make her side characters into real people, even if they were also Comically Stingy Scotsmen or Childishly Innocent Negro Clergymen.

One of my favorite books by L.M. Montgomery is called A Tangled Web. I love it. It goes along smoothly, and then, whammo - almost the last word in the book is a shocking racial epithet. Nngh.
