Ambrose Bierce 
Watcher by the Dead 

Dr. Helberson and his friends, Harper and Mancher, are enjoying a night of smoking and drinking in the good doctor’s office when a question arises. Is a fear of the dead curable? The doctor believes it absolutely is and sets about organising a wager with his friends. They find a local gambler named Jarette and bet a large sum of money on whether he can spend the night locked in a room with a corpse without losing his mind. A haunting tale full of monstrous imagery, which deftly displays Bierce’s terrifying mastery of the horror genre. If you loved ‚The Conjuring‘ you will love this classic ghost story.-
