Who is sabotaging the Rainhill Trials?It is 1829. Everyone is talking about the exciting new railways and young Edward Entwistle cannot believe his good fortune: a chance encounter sees him offered a job at the Stephensons' Steam Locomotive Manufactory. The Stephensons are preparing for an important competition - The Rainhill Trials. A race of innovation and daring which will award the winner a contract to run the new Liverpool & Manchester Rail Way. Edward must protect the father and son inventors' latest creation - their precious Premium Engine - but strange and dangerous accidents keep stalling construction. Edward and his new loco-mad friend Prudence soon realise someone is trying to scupper the Stephensons' chances. It is up to the friends to spot sabotage and chase down spies in a thrilling race against the clock. Inspired by the Rainhill Trials.
