The Pharaoh's Golden Casket

In 1279 BC, the goldsmith Huja is commissioned by Pharaoh Ramses II to make an elaborately jewelled golden casket. This is a great honour for the craftsman, and he is the envy of many, but it also puts him in a perilous position. If the work is not finished in time, he is in danger of severe punishment. When the Pharaoh's treasures are loaded onto a ship, the golden casket suddenly disappears without trace. Can Huja's children, who have been keeping a close eye on the proceedings, find a way to help their father?
