"The Trade in the Dead"
This is non-faction account. Like "A Ghostly Connection" - quite a different tale - this shows that Haggard could express very forthright opinions about something in which he believed strongly. This is essentially about the desecration of Egyptian graves. The million or so tombs of departed ancient Egyptians were a rich plundering ground for generations of people, from the ancient Egyptians themselves, to their modern descendants, and European scientists.
Not that Haggard is under any illusions as to the nature of the remains themselves. As he remarked, the corpses themselves often "affront the sunlight with the horror of their shrouded bones". Pharaoh Amenophis II had a "royal though somewhat ghastly countenance". But of the rest (except Seti an Rameses) "all are repulsive, and some are horrible to see'. The distorted withered corpses were carried down the Nile to the Cairo Museum, there to be preserved and exhibited, while the ordinary Egyptians bowed their heads as the remains of the past Kings went by. But Haggard thought that they should be treated with due respect.
He called for them to be left where they were, on the grounds that the Egptians have as much entitlement to the sanctity of the sepulchre as anyone.
"Smith and the Pharoahs" is a fictional sequel.
