The Evil Guest by J Sheridan Le Fanu

Le Fanu's inimitable style continues with The Evil Guest, a murder mystery fraught with dark imagery and mysterious characters.
An unwanted guest visiting a dreary and isolated home is murdered; the thriller leads the reader down countless 'dead' ends before revealing the identity of the guilty party.
The letter from the rich cousin came at a low point in the Marston family's finances. The man was as ill-bred and pushing as ever: utterly the model of a noxious relation - but he was rich, and the Marstons were all but destitute. The family could hardly refuse him. But they would come to rue that letter, and the invitation that followed it; it was the beginning of the end for all of them. Of course it was! Common sense tells us not to take on . . . THE EVIL GUEST.The Evil Guest was first published in 1895.
