27. The Tenth Doctor Meets a Soul Mate
From: "The Girl in the Fireplace"
Premiere: May 6, 2006
On a derelict spaceship, the Tenth Doctor and his companions discover a time window (in the form of a fireplace) that leads to the 18th-century bedroom of Madame de Pompadour, mistress to King Louis XV of France – targeted in the machinations of elegant but deadly clockwork robots. Not so much a historical adventure of the kind the First Doctor commonly encountered, "The Girl in the Fireplace" is effectively a ravishing love story for David Tennant and his pitch-perfect cast mate, Sophia Myles.
