From the bestselling author of Horrible Histories... The great inventor Archimedes has just one problem. His clumsy servant, young Lydia, is the bane of his life. But when the Romans besiege Syracuse, and the Greeks turn to Archimedes for help, it is young Lydia who always seems to come up with the answers. Of course Archimedes is a lion in the eyes of the folk of Syracuse. He takes all the credit, but that's life for a Greek girl slave. Terry Deary's...
