'If Philippa Penhow hadn't gone to Bleeding Heart Square on that January day, you and perhaps everyone else might have lived happily ever after...' It's 1934, and the decaying London cul-de-sac of Bleeding Heart Square is an unlikely place of refuge for aristocratic Lydia Langstone. But as she flees her abusive marriage there is only one person she can turn to - the genteelly derelict Captain Ingleby-Lewis, currently lodging at no 7. However, unknown to Lydia, a dark mystery haunts 7 Bleeding Heart Square. 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? And why are 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 - but is there now a new and sinister presence lurking in its shadows?
