On the Gebel el Silsila site is a Necropolis. John and Maria have discovered what looks to be a tomb. John wants to check the space for salt damage (the site is regularly flooded by the Nile) so he needs to crawl inside and have a look. The bones and pottery he discovers convinces him he’s in a tomb. Then, he discovers a man made opening at the back of the tomb, leading to another chamber.
