"Heaven Sent" is the eleventh and penultimate episode of the ninth series of the British science fiction television series Doctor Who. It was first broadcast on BBC One on 28 November 2015. It was written by Steven Moffat and directed by Rachel Talalay.

In the episode, the Doctor (Peter Capaldi), in the wake of Clara Oswald's (Jenna Coleman) death, has been teleported to a strange waterlocked castle, and is there pursued by a shrouded creature that is trying to kill him. The episode received universal critical acclaim, with many stating that it was one of the strongest episodes of the new series and of the show overall. Special attention was given to Capaldi's acting, Moffat's writing, and Talalay's direction.

After witnessing the death of his companion Clara Oswald in "Face the Raven", the Doctor is teleported into a glass chamber located in a structure resembling a large castle operated by clockwork gears. Still emotionally shaken by Clara's death, he angrily speaks aloud to the entity that put him there, assuming that they are listening. The Doctor knows the distance that the teleporter is capable of sending him and he plans to wait until the stars come out and work out his location. Upon investigating the surrounding corridors, he finds a series of video screens scattered around the castle. The screens relay the vision of the Veil, a cloaked creature which is slowly and constantly stalking the Doctor around the building. The Veil chases the Doctor to a dead end. Admitting that he sees no way to escape death, the Doctor confesses that he is afraid to die, leading the creature to stop. The entire castle structure rotates and reconfigures in response, opening an exit at the end of the corridor that the Doctor was trapped in, beyond which is a bedroom with an ancient, faded portrait of Clara. The Veil follows the Doctor into the room, forcing him to leap out the window to escape. During his leap, the Doctor has an inner monologue, determining how he will survive the fall by imagining himself aboard the TARDIS answering questions written on a chalkboard from an otherwise-silent Clara. The Doctor lands in an ocean surrounding the castle, finding that the seabed is littered with thousands of skulls.
