The Wallpaper That Killed Napoleon?

A little scrap of wallpaper that might have helped kill Napoleon has been sold at auction. “Tests eight years ago, on a lock said to have been cut from Napoleon’s hair after his death revealed eight times normal levels of arsenic. One culprit could have been the red-and-gold wallpaper of his bedroom, at Longwood House on St Helena, where he was exiled for six years until his death in 1821.”
