Go, lovely Rose1954

"Rachel Buckmaster returns to the small town of Coreyville, where she and her brother Hartley grew up, following the death of Rose Henshaw. Rose had been living in Rachel's family home, thanks to a mystifying provision in the will of Rachel's late father. Mystifying because Rose was a nasty piece of work. Rachel had been glad to escape her influence, and she fears that Rose's spiteful nature may have driven Hartley to pushing the old woman down the cellar stairs. For Rose's death means that the siblings can now cash in by selling the house. Soon it becomes apparent that Hartley was not the only person with good cause to wish Rose ill."
