Angela Gallop has been a practising forensic scientist in the UK for more than 40 years and has a CBE for services to the field.
During her career, she has provided critical evidence to prosecution teams - not only leading to the conviction of perpetrators but also in cases where there have been miscarriages of justice.
Her work on some of the UK's most high-profile cases, including the killings of Stephen Lawrence and Rachel Nickell comes to life in her memoir When The Dogs Don't Bark.
