Elephants and Castles

How can a school boy be Britain's most wanted terrorist? Thirteen-year old Elvis moves to his step-father's crumbling London home and is confronted by apparitions from the Black Death of 1665. Somehow he's got to get them back to where they came from, but in the process he catches plague himself and ends up in hospital. Soon half of London is sick and police track the illness back to Elvis's door.
