It’s 1934, and the decaying London cul-de-sac of Bleeding Heart Square is an unlikely place of refuge for the well-bred Lydia Langstone.

What happened to Miss Penhow, the middle-aged spinster who owns the house and who vanished four years earlier? Why is a seedy plain-clothes policeman obsessively watching the square? What is making struggling journalist Rory Wentwood so desperate to contact Miss Penhow?

Parcels of rotting hearts being sent to Joseph Serridge, the last person to see Miss Penhow alive. Legend has it the Devil once danced in Bleeding Heart Square. And now there is a new and sinister presence lurking in its shadows.
