With unfinished business to attend to, the Seventh Doctor returns to where it all began- Coal Hill School in London in 1963. Last time he was here, the Doctor left something behind - a powerful Time Lord artefact that could unlock the secrets of time travel. Can the Doctor retrieve it before two rival factions of Daleks track it down? And even if he can, how will the Doctor prevent the whole of London becoming a war zone as the Daleks meet in explosive confrontation? An adventure featuring the Seventh Doctor as played by Sylvester McCoy and his companion Ace

Andrew Brown never has enough time. No time to call his sister, no time to prepare for that important presentation at the bank where he works... the train's late, the lift jams, the all-important meeting's started by the time he arrives. Disaster. If only he'd had just a little more time. Time is the business of Mr Symington and Mr Blenkinsop. They'll lend Andrew Brown some time - at a very reasonable rate of interest. If he was in trouble before he borrowed time, things have just got a lot worse! Detecting a problem, the Doctor, Amy, and Rory go undercover at the bank. The Doctor's a respected expert, and Amy's his trusted advisor. Rory has a job in the post room. But they have to move fast to stop Symington and Blenkinsop before they cash in their investments. The Harvest is approaching!
