The Hippopotamus Pool

Like the previous book in this series, this one is more gripping than amusing. But this time everyone is assembled in Egypt: Ramses and Nefret are present, and Walter and Evelyn too. There is some serious archæology: a fascinating new tomb is discovered. But there are also menacing criminals to be dealt with.

A new character is introduced, the boy David.

I think this is one of the better books in the series, but I still hesitate to give it four stars. Three and a half, perhaps...
