Paul Daneman reads Enid Bagnold's story here. Be warned - there is a reference to stays. It's an interesting story, not just because it takes a slightly naughty tack on the familiar haunting theme. It also omits to give a reason for the haunting. It's likely that Bagnold thought of the ending first (or perhaps dreamed it) and then worked backwards. It certainly veers between country house comedy and something more disturbing.
