So I’m reading a mystery novel, and the heroes are talking to the medical examiner about what she’s learned from the as-yet-unidentified murder victim.

The ME gives a quick rundown of the useless information she’s gathered so far, including the detail that the deceased “flossed conscientiously.”

I did not fling the book across the room, but I winced. You see, the reason they hadn’t yet identified the body was that the head was missing. I’d like to know how you can tell someone flossed regularly from looking at her headless corpse.

I can’t believe nobody caught that. What was the copy editor thinking?
