Denise Fergus and her two-year-old son James Bulger had been out shopping when she let go of his hand for a split second. His killers, two 10-year-old boys called Robert Thompson and Jon Venables, abducted little James and brutally murdered him. The crime forced people around the world to re-think what children could be capable of. Now, 25 years on, Denise has written a book called I Let Him Go which tells her traumatic story in full for the first time. She tells Matthew Bannister about the struggle to overcome her son's death.
