The full, true story of the dog featured on the cover of Clare Balding's HEROIC ANIMALS

Firefighter Paul Osborne works with the Fire Investigation Dog unit, where he handles Sherlock - an excitable, bright-eyed cocker spaniel.

What makes Sherlock different? He's the most talented investigative dog the Fire Brigade has ever produced, capable of identifying extraordinarily subtle traces and scents even after thousand-degree blazes - even when he has to wear special protective boots due to the dangerous environments.

Today, Paul and Sherlock fearlessly plunge into the most dramatic fire scenes in London, helping to keep the capital safe around the clock. With remarkable insight into the life of London's most heroic working dog, this inspiring account of the London Fire Brigade's four-legged heroes will delight and amaze.
