 Ben Bunsen was the owner of a vintage car, which was known as "the Burner" because it was so old it was steam-driven!Like an old-fashioned steam train it had a boiler which had to be stoked, as it ran on coal instead of petrol.Ben and his pal had to drive the Burner around the world, as a condition of Ben inheriting his uncle's fortune; but a rival claimant (shades of "His Sporting Lordship"!)
