Series 3 Episode 12: The Sound of Drums

Summary:
The Doctor, Martha and Jack manage to get back to earth with the help of Jack's vortex manipulator. There, Martha finally recognises the voice of the Master, who is no other than Harold Saxon, the new Prime Minister of Great Britain. He seems to know that the three are back because there is a bomb in Martha's flat and they have to go into hiding. Martha's mother has helped Saxon to find her daughter but when they are all taken, she shows some bravery and tells her daughter to run. Jack reveals that he's the leader of Torchwood but he can convince the Doctor that the organisation has changed. The three are able to follow the Master with a perception filter in form of the Tardis key and soon land on a UNIT spaceship. There they find the Tardis but the Master has turned it into a paradox machine and the Doctor has to find out what it is for before he can do anything. The Master is able to rip a whole into time and imprison everyone on board of the ship except Martha, who uses Jack's vortex manipulator to teleport back to earth.

The interaction between the Doctor and the Master is just brilliant in this episode. They are perfect enemies because they know each other so well and you just feel that there was a good chemistry between the actors. This episode leads to the final episode of the tree-parter and produces just the right setting for a brilliant series finale. There are so many hints about what will happen but not so many that you can find out everything easily. We can see what a cruel person the Master is but maybe he would have been different without the drumbeat in is head. I think the Doctor, Martha and Jack are great together and it just feels right that they are fighting together. David Tennant in the mask of an old man looks amazing and he still manages to keep the essentials of the Doctor in this form. A great episode, which wants you to know what happens next
