A marriage is what you make it, isn’t it? It’s what you put into it. It’s not just about love, it’s about understanding another person’s point of view. Sometimes there are things you find out about yourself and each other which means the marriage has to end. Sad, particularly when kids are involved - but all pretty normal.

Normal that is, until there’s a murder.

DS Jane Bennett and DI Mike Lockyer are called in to investigate one of the South London murder squad’s most difficult and distressing cases yet - where family and friends come under scrutiny in the hardest of circumstances.
