Knight of the Old Cart

A policeman recognizes that a serial killer is recreating Botticelli's Primavera with the corpses because he remembers this lady's exposed left breast. But in the real painting, her arm covers her boobs, and the diaphanous dress kinda does too. The left boob is just not particularly distinguishable (sorry).

One of the chapters begins with a quote from The Squire's Tale (she who sups with the devil needs a long spoon), but the book attributes that quote to The Merchant's Tale.

The policeman are playing Super Mario Bros on Hannibal's computer, but you can't play Nintendo games on PC. (They might be playing a fan port from that era called Mario Forever.)

There might be more mistakes; I haven't been looking for them. There are a ton of references and details in this book, and I don't look them all up.

"Can you walk? Are your legs working?"

"Yes."

"Can you see alright?"

"Yes."

"I'm gonna cut you loose. With all due respect, doctor, if you fuck with me I'll shoot you dead here and now. Do you understand that?"

"Perfectly."

"Do right and you'll live through this."

"Spoken like a Protestant."

I noticed this when I watched Manhunter (1986) and Red Dragon (2002), which adapt the same book. The characters have to closely read multiple letters, either to decode them or under duress. In the 80s movie, you get to feel the same intrigue/confusion/fear the characters feel as we read these creepy letters together. And the letters are not too long, and the characters read them out loud anyway, so it's not like it's a big reading challenge. In the 00s movie, you get to see some bits of the letters under microscopes, but not much more than that.
