William the Conqueror is back in his tomb waiting for another set of looters to grab as much colour-coded treasure as they can - did we mention that his guts would explode? There are WW1 words to decipher and enough garum sauce to fill several Roman cauldrons. Dave and Rattus are around to make sure there is fair play.
Dave is pretty fed up with Rattus' new game Plopscotch. He's definitely going to need a change of shirt. The Horrible Historians try to work out how to build a pyramid and make two identical portraits of Queen Elizabeth. They watch out for Emperor Vitellius, and a cauldron of truly horrible Garum Sauce.
