The Gold In The Grave (English, Paperback, Terry Deary)

Tutankhamen has been buried in his rocky tomb. But there is a plot to rob the grave of its vast wealth as soon as possible after the funeral. A motley gang of villains have all the skills they need to undertake the crime – the key member of the team is young Paneb, who is small enough to slip through the tunnel and into the funeral chamber.
