We watch "Blink" (Series 3, Episode 10) where the Doctor and Not Rose travel to London for the Easter Eggs. Whilst there, we meet Sally's Angels: Kathy, the Bumbling Angel; Billy, the (too) Inquisitive Angel and Larry, the Blond One. The Angels are called in to solve the Mystery of the Disappearing Car Owners. Spoiler warning: the Angels did it. And they would've gotten away with it too if it wasn't for those meddling Angels!
