I saw Army of Ghosts for the first time last night. I noticed in the Torchwood institute's 'warehouse' an Egyptian sarcophagus. Is this supposed to be anything to do with the sarcophagus in 'Pyramids of Mars'?

I took it as such.

Oh, I never noticed that. I shall look out for it, the next time Army of Ghosts in on TV. Sky channel 'Watch' will be showing this next week. They are up to the Cyberman two-parter at the moment, when the Doctor and co got temperarily stuck on an alternate Earth.
