Welcome to The Fun Factory: trespassers will be self-prosecuted.

The Valeyard (aka The Flaw Doctor) makes the most of a unique Time Lord feature and gives his own SJW predecessor a right legal leathering on Space Station SFX.

But they still find time for trips to Camber Quicksands and Popplewick's House of Exploding Quills, where the waiting room is spacious but gives you that sinking feeling.

The Doctor quotes, the Master gloats and Glitz dotes on bank notes, while the Keeper is not averse to the odd slide tackle to protect his Panatropic Net (even though Mel always aims for row Z).

But did Jim and Martin find The Ultimate Foe ultimately forgettable or a worthy way to end an era?

Listen to find out.

The lads also review the audiobooks of The Krotons and The Curse of Fenric.
