Writers have been killing themselves for centuries. From Petronius in ancient Rome to the 20th Century Japanese novelist Yukio Mishima, writers, more than any other kind of artist, have taken their own lives in an extraordinary number of ways. With bullets, poison, drugs and swords, poets, playwrights, novelists and philosophers have sent themselves off into the big sleep. Others, one step shy of that last exit, have made great literature about the urge to self-destruction.
