William Hope Hodgson 
Carnacki, The Ghost Finder [EPUB ebook] 

William Hope Hodgson, an English author, collected occult detective short stories under the title Carnacki the Ghost-Finder.
The Grey Room, a chamber in an old mansion, was the scene of a gruesome murder many years ago. He underestimates the strength of the manifestation, and he spends a wretched, terrifying night within his electrified pentacle. In Ireland, a derelict home exhibits paranormal activity, including what seems to be blood falling from the roof. Carnacki assembles a team of strong neighborhood guys and many dogs for the investigation. According to a Celtic tradition, a court jester was once burned to death while whistling in the fireplace of the chamber. The chamber is then completely destroyed, with all of its components being burnt in a blast furnace inside of a protective pentacle that features an old Celtic inscription. There is a female firstborn for the first time in seven generations, and her fiancée has just had her arm shattered by an unidentified attacker. Carnacki looks into a haunting that has occurred at his mother’s home. The tenant informs Carnacki about the house’s enigmatic past and rumours of a ghostly woman. Carnacki spends the night at the chapel dressed in armour, his camera at the ready to capture any enigmatic occurrences. He had been hearing strange noises all night.
