Mansion by Derek Barley

You have just inherited your great aunt Agatha's English mansion, Gharston Hall, a rambling monstrosity built in the 17th century. But as you start looking around your new home, a Mr. Brookes lets himself in, claiming that Agatha sold Gharston Hall to Perfidia Properties for the development of a hotel and leisure complex. He also insists that you pack up the last of Agatha's things and vacate the place by midnight. Something fishy is going on, but what can you do about it?
