The final installment of the Watts family adventures is the most action-packed yet! Once again, Danny Watts and his grandfather Fergus are on the run. But when Dudley, a top MI5 agent, tracks them down for help with a new mission, they finally have the chance to clear their names once and for all. Danny and Fergus must find the makers of a dangerous new drug called Meltdown and destroy it before it can enter the mainstream, or even worse, fall into the hands of a radical terrorist group. But in order to do this, they must infiltrate the drug production network and once again get behind enemy lines, even fighting alongside their nemesis, Special Agent Deveraux. After all that they have been through, will Danny and Fergus finally be able to stop running? Filled with all the action, excitement and SAS special operations techniques that have kept this series on the UK bestseller lists, Meltdown completes the Watts saga in grand fashion.
