In Baby X we learned how super-tough cop Harry Keeble and his colleagues in Hackney's Child Protection Unit rescued dozens of kids, faced lynch mobs and undertook the impossible job of interviewing paedophiles.
Now, in Little Victim, Harry takes us through an extraordinary year in the life of the unit, as the team investigates some of the worst cases of child abuse they've ever encountered.
These include a middle-class mother who shook her baby to death, the children kept in a cage, the rape of a three-year-old boy and an innocent grandfather falsely accused of paedophila.
Little Victim provides a unique insight into the complex issue of child abuse in the UK.
Continuing his battle to bring Britain's child abusers to justice, Harry is pushed right to the edge as he confronts horrors past and present.
