The Best Episodes Written By Ben Aaronovitch

With two factions of Daleks involved in a race war on Earth, the Doctor takes care of old business by having the Hand of Omega ceremoniously but quietly buried in a churchyard. His actions do not go unobserved, and leaving behind a bored Ace without a purposeful outlet could spell trouble as well.

The Doctor plans to let one of the Dalek factions have the Hand of Omega (but not too easily, of course) while keeping Gilmore and his military men preoccupied in a safe territory, but that plan could be threatened by a mole in their midst and a miscalculation on the Doctor's part.

The Doctor and Ace discover a stone spaceship underneath Warmsley's archaeological dig while Mordred summons Morgaine to Earth's dimension.

London, 1963. Returning to the scenes of his first televised adventure, the Doctor and new companion Ace play a tricky game of bluff and deceit involving two rival Dalek factions, local soldiers, and the awesomely powerful Gallifreyan artefact, the Hand of Omega...

As UNIT are transporting a nuclear warhead around Carbury, knights in armour arrive to continue waging a war that began thousands of years ago, but in a wholly different dimension.

The Brigadier rescues the Doctor from the stone spaceship before they set out to locate Morgaine before she gains Excalibur.

Morgaine forces Ace and Shou Yuing to hand over Excalibur by threatening to release the Destroyer, so the Doctor and the Brigadier enter a dimensional portal to stop her.
