A special solo adventure for Colin Baker as the Sixth Doctor, in the second of three stories dealing with the Doctor's latest battle with arch enemy the Master. Somewhere off the South Coast of England, there's a lonely island. On that island stands a solitary castle, long since abandoned - haunted, they say. But the truth is, that castle houses something far worse than mere ghosts. The castle is what lies at the end of a trail followed by the Doctor in search of several missing scientists - all of them connected to the top secret Dominus Institute and its elusive CEO, Sir Andrew Gobernar...But the Doctor will soon discover that he's the one being haunted, by a ghost from his past...or perhaps, his future. Big Finish's main range of Doctor Who stories began in 1999, and has featured television Doctors Peter Davison, Colin Baker, Sylvester McCoy and Paul McGann across its 212 tales. Writer Justin Richards has worked in a variety of roles connected with Doctor Who, including a number of novels for the BBC. He's also the writer and creator of The Invisible Detective series of books.

Alex Macqueen first appeared as the Master in Big Finish's Doctor Who spin-off UNIT: Dominion, going on to confront the Eighth Doctor (Paul McGann) in the hugely successful Doctor Who - Dark Eyes series.
