Kerry is shocked to discover that Jagger was killed by a cocktail of illegal pesticides.

The toxicologist in Ghent reveals how this same poison is used to protect multi-million-dollar racing pigeons from birds of prey.

The head of the RSPB reveals how in the UK this poison is being illegally used by game keepers in the UK too.

Jagger is not the first dog to have been killed by poison bait. Chloe Ambler’s two dogs both consumed what is known as ‘the Nidderdale cocktail’ due to its prevalence.

This was no accident. A human had sewn it into meat. For a dog. But was Jagger the dog in the killer’s sights?
