Tom Baker: Towards Zero

Our favouite Doctor appears in the episode of Agatha Christie's Marple called 'Towards Zero'.

In fact he lends the story its name whilst observing that the lives of all present have been 'converging towards zero' prior to the first death.

Despite playing a man with a serious heart condition (not serious enough to stop him drinking copiously!) he manfully resisted the urge to shout “Call me a Doctor” . . .
