With new-found friends in Penzance, the Lawrences try to solve a mysterious riddle they stumbled upon on their way to a camping holiday in Cornwall.
But they soon realise that there are enemies about, and they must fight to outwit the opposition, as the treasure hunt hots up.
But the race is on to reach the treasure first...if they can only solve the riddle and outwit their enemies.
This children’s’ holiday adventure is set in modern times but draws on a classic genre of teen adventure book. The action takes place in real places you can visit for yourself.
