Cairo is a location in 80 Days. It is situated in northern Africa and is the capital of Egypt. The city adopted the 'Parisian model' of modernisation, resulting in a cultural hodge-podge. Passepartout may meet Sophos again following their earlier European encounters and hand him the Venetian glass he obtained from the Sophos Company warehouse in Antalya. Although he won't reward Passepartout with another two thousand pounds, he will reward the valet with a Mechanical Lily worth a considerable sum in another part of the world, provided they arrive there.
If he has already stopped in Alexandria before, Passepartout will reunite with Helena Kapodistrias, the scientist he met experimenting with a projector that can see into the past.
