Intro: Tonight, a Doctor Who adventure that proves that it takes brains to go to a bathhouse. The enigma The Doctor and Peri must solve is who's taking the brains. We will learn soon enough when we meet a renegade Time Lady in "The Mark of the Rani."

Outro: Next week, The Doctor feels the death of an earlier form and concludes that an earlier self must have been taken out of time. His deduction is correct and leads to a meeting of "The Two Doctors," next Sunday night at 11. [source: ChicagoEpguides]
