Guillotine

The guillotine was a device used in executions. It was frequently used by revolutionaries in 18th century France to dispose of their enemies.

In 1789, a young French aristocrat named Jason (a.k.a. Marquis de Saint Epiman de Sinee de la Tour) was sentenced to death by guillotine but was rescued by the Sixth Doctor and became his companion. Later, the meddling of a Dalek caused the TARDIS to return to revolutionary France. Jason was arrested once more and his sentence was almost carried out but he managed to escape again.
