Those who wailed about the centuries-delayed vengeance of a dead man now hide their faces in shame. Testing reveals that the mummy was indeed the cause of the tragedies that befell those associated with it – because it was coated in ancient bacteria, grown upon long-since decayed food interred alongside it. We now know that this affects both the wits and the guts, but fortunately we can also treat it easily. You need fear the pharaoh's curse no longer – and need nor anyone else. There is much rejoicing (and hilarity).
The entire land seems to exhale in relief – not only that the 'curse' is ended, but also at this unqualified triumph of science and reason.
