A visitor to the Smeaton's station in rural Victoria, Mr. Eyton, hears from Mrs Smeaton the tale of Mr. Smeaton's first wife and her wild-living daughter who had been disinherited in favour of Mr Smeaton - who had subsequently left all his money to his second wife, Mrs Smeaton, his former house-keeper. A threatning midnight visit from his first wife's daughter induces Mr. Smeaton to change his will - but then he is murdered before he can change it again. Mrs. Smeaton is arrested but Melbourne detective Lanigan reveals Mr. Eyton to be the daughter in male disguise. Strychnine aplenty. (PB)
