Taking Steps by Alan Ayckbourn

Roland is considering buying a reputedly haunted house. His solicitor and the vendor come to the house one evening to complete the deal. Also in the house are his wife, who is considering leaving him; her brother, called to help her take this difficult step; and the brother’s fiancée.

During one hectic night everyone’s expectations hilariously unravel and rearrange themselves in unforeseen ways.
