In 1860, old Alice Barlow was found brutally murdered in her London home. The motive was thought to be the priceless Barlow Rubies, but the murderer was never caught and the jewels were never found.
Now, twenty years later, the same house is occupied by elegant Jack Manningham and his nervy wife, Bella. Bella believes she is losing her mind. Objects – including paintings – disappear, only to be found later hidden around the living room. Frustrated by what he sees as her weakness and need for attention, Mr Manningham seeks daily refuge at his club, leaving his wife to sit in terror as ghostly footsteps move above her head and the gaslights flicker and dim.
One foggy afternoon, Bella receives a visitor in the form of a mysterious stranger called Rough. But what is the purpose of Rough’s visit? Is Bella Manningham really who she says she is? And what is her connection with the missing Barlow Rubies?
