TEXT: THE HAND OF FEAR BY: BOB BAKER AND DAVE MARTIN Part Four Running time: 25:00 [SCENE_BREAK] ELDRAD: The traitors. I should have expected. DOCTOR: Eldrad, what was in this tube? ELDRAD: An acid designed to neutralise the molecular bond. It is now only a matter of time. DOCTOR: Is there an antidote? ELDRAD: Oh no, Doctor. I developed the acid. There is no antidote. DOCTOR: But there must be something? ELDRAD: Regenerator chamber, level three zero six. But you must get me there quickly before it shatters the crystal matrix. Quick, quick. SARAH: Wait, I'm coming. [SCENE_BREAK] COMPUTER: Intruders penetrating level fifty and descending. Intruders penetrating level one hundred and fifty and descending. [SCENE_BREAK] DOCTOR: Level three oh six. SARAH: How can you tell? DOCTOR: Worked it out from the indicator. It's all based on roots of three. SARAH: I hope that regenerator isn't far. DOCTOR: Which way, Eldrad? ELDRAD: That way. DOCTOR: Come on. [SCENE_BREAK] COMPUTER: Intruders on level three zero six identified as two aliens, one Kastrian. [SCENE_BREAK] DOCTOR: Sarah! ELDRAD: She is unharmed, Doctor. These traps are only effective against silicon-based lifeform. DOCTOR: Come on, Sarah. Stop making a fuss, Sarah. You're from South Croydon. SARAH: Eh? DOCTOR: You're a carbon-based lifeform. The gas is only effective against silicon structures. SARAH: Oh. DOCTOR: Come on. SARAH: Hang on. The least you could do is wait for me. I nearly frightened myself to death back there. DOCTOR: Yes, I know. It's that way. SARAH
