"The Chariot"

From Tardis Wiki, the free Doctor Who reference
The Chariot

"The Chariot", or "Because I Could Not Stop for Death", was a poem by Emily Dickinson. It went,

Because I could not stop for Death
He kindly stopped for me
The carriage held but just ourselves
And Immortality.

Once inside Torchwood Three, Max Tresilian chanted it to send the Hub into lockdown. (TV: They Keep Killing Suzie)
