The Little Stranger is a 2009 gothic novel written by Sarah Waters. It is a ghost story set in a dilapidated mansion in Warwickshire, England in the 1940s. Departing from her earlier themes of lesbian and gay fiction, Waters' fifth novel features a male narrator, a country doctor who makes friends with an old gentry family of declining fortunes who own a very old estate that is crumbling around them. The stress of reconciling the state of their finances with the familial responsibility of keeping the estate coincides with perplexing events which may or may not be of supernatural origin, culminating in tragedy.
