In 1814, the 74-year-old writer Marquis de Sade sits in the locked ward of a Parisian lunatic asylum. But neither prison nor his age prevent him from continuing to outrage and terrify the world. Jacques Chessex recounts de Sade’s last months with wit and ribaldry. And he talks of how de Sade’s skull, revered as a relic, made a curious journey through the centuries. The Swiss author depicts an impressive literary portrait of one of France’s most fascinating and offensive heroes of the Enlightenment.
