First of a two parter to start off Series 3. A man called Mc-hage's business is desperately trying to be sabotaged, and he calls in Ros, Ed and Beckett to investigate. It turns out that just recently, Mc-Hage's son, Christopher, committed suicide and Ed goes to see Mc-Hage's daughter, Kitty Mc-Hage, to find out more about the business.

Ed ends up getting blown up with the ‘wagon'
