“Come on, old girl!” shouts the Doctor smacking the side of the central column of the Tardis’ console which is emitting an unpleasant screeching sound as it rises and falls.

“Is everything all right? Doctor,” I yell over the noise, gripping the edge of the console to steady myself as the Tardis bucks and pitches.

“Um, yes, just needs a minor correction.” He frowns at the column and flicks a couple of switches. The Tardis comes to an abrupt halt and all is quiet “Come on, let’s see what’s happening outside.” He motions me to stand beside him, then with a flourish he taps a button on the console. A large viewing screen flashes up on the other side of the control room.

The screen is blank.

“Ah,” he says tapping on the button repeatedly. Nothing happens. The screen is still blank.

The Doctor rushes over to the doors and flings then open.

All is black.

I follow him and peer out. “Oh,” I say. There is literally nothing there. I turn to the Doctor who is rubbing his jaw. “Where’s space gone?”

“That, Jemma, is space.” He leans out of the doors looking up and down. “Space. Nothing else.”

“But the stars and…”

“I better check the coordinates,” he says over his shoulder as he runs back to the console. “Close the doors won’t you?”

I pull the doors closed. My heart thumps. “What’s happened to Harris and Stevens? Are they all right?”

“I certainly hope so.” He pulls out his sonic screwdriver and disappears under the console.

The viewing screen flickers into life showing a view of my two shipmates sitting just where I’d left them on our spacecraft. Both have expressions of extreme concentration on their faces. In the background I can see what they’re staring at. I blink in surprise.

They’re playing the ancient arcade game ‘Space Invaders’!

The Doctor reappears from beneath the console. “That should do it. We should be able to see them now.” He glances at the screen as the Tardis shudders under a sudden impact.

“No, NO,NO, NO!” he shouts.

I turn to him, not understanding what’s happening. The Tardis shudders again; sparks fly from the console. The Doctor points at the bottom of the screen the boys are staring at. “They’re firing at us!”

We watch as the little white aliens descend towards the Tardis.

The boys are firing back.

“No Doctor, they’re defending us.”

Or at least they’re trying to…

Will the Harris and Stevens beat the aliens? Can the Tardis escape from the game?
