Entanglement is a First Doctor audio adventure narrated by and starring Peter Purves and Maureen O’Brien, who play companions Steven and Vicki.

The story is set in Cambridge in the mid-1930s. When the Doctor, Steven and Vicki get separated from the TARDIS they’re forced to spend time amongst the ancient spires of Sedgwick College. The college is midway through a leadership crisis following the unexplained disappearance of the Master of Sedgwick, Sir Isaiah Hardy. An election for his replacement is now taking place.

But that’s not all that’s happening in this seemingly peaceful location. The proctors are behaving in mysterious ways and the students are prone to bursts of unexplained violence. When one of his companions also vanishes, the Doctor realises there’s more at stake than control of an educational establishment. A dark plan is underway…
