Micky Yule is a double amputee on a mission to take on the seemingly impossible. Now, in the run up to the Winter Olympics, he's got his sights set on one of the fastest, most dangerous ice sports of all - skeleton.

On 9 July 1996, three bodies were found in a little leafy copse beside a country lane in Chillenden, Kent. Dr Lin Russell, 45, and her two daughters, Megan, six and Josie, nine, had all suffered brutal head injuries caused by a blunt instrument. They had been tied up and their family dog, Lucy, was also found dead nearby.

They’ve been man’s best friend for thousands of years. But how much do we really know about our dogs and where they came from?
