In southeast London, a young mother has been accused of an unthinkable crime: poisoning her own child — and then leaving him to die. The mother, Ellie, is secretive and challenging — she's had a troubled upbringing — but does that mean she's capable of murder?
Balancing the case with raising her disabled five-year-old son, criminal defence lawyer Sarah Kellerman sets out in desperate pursuit of the truth. But when her own child becomes unwell, Sarah realises she's been drawn into a dangerous game.
Unsettling and compulsive, In the Blood is a chilling study of class, motherhood and power from a new star in crime fiction.
