On a warm April morning in 1906 a crowd of expectant correspondents from London's leading newspapers gathered at the Hotel Cecil in the Strand to view the new wonder of the age - the electrobus.

This clean, green machine was gearing up to take on the noisy, polluting petrol vehicle, which was just starting to replace the horse-drawn omnibus and surely had the potential to be a game changer in terms of what it would mean to Londoners and other city-dwellers who were already choking on petrol fumes.

Disastrously though, the London Electrobus Company was in the grip of a gang of greedy and fraudulent financiers, who systematically conned shareholders, looted the company's coffers and drove the promise of the electrobus into the ground.

Rammed with fascinating characters and vividly capturing the Edwardian era, A Most Deliberate Swindle uncovers one of the biggest frauds in history and reveals why a century later this historic scam has left us all gasping for breath.
