Book 20 in the series takes the time-travelling foursome on a journey that will eventually lead them to the home of one of the great scholars of the 18th century - Dr Samuel Johnson, the compiler of the first ever English dictionary. But there's more to this adventure, as the youngsters discover that slavery in the 1750s was much closer to home than they ever realised.

When a ship from the Caribbean arrives in 18th-century Bristol, a young slave boy seizes his chance to escape. As Cuffey flees through the docks he meets three children and their cat who are far from home in more ways than one. They haven’t come from another country, but another time – the 21st century.

Together, the young time-travellers and the runaway slave embark on a journey that takes them across the country to London… and the start of a gripping adventure.
