The Unexpected Guest

A cripple lies murdered in a wheelchair and the wife is holding the revolver in a house where almost everybody has a motive to be the killer. But interestingly, a stranger who is stranded due to his car getting into a ditch, stumbles upon the household and plans a misdirection for the authorities to save the wife of the charges. But will the truth be so easy to hide? Will the murderer get away? As the story progresses, the apparent clear case seems to develop in a mysterious murder which is actually noted in the excerpt of Osborne's analysis on Christie fictions annexed as a standalone chapter. The mystery was well conceived though the climactic twist seemed a bit too bland. This novelisation suffers from the fact that the author could not give an original touch in places where it seems more like a play rather than a novel.
