It's a spooky, unsettling nightmare for Jo Grant in this month's Doctor Who Companion Chronicle, Ghost in the Machine.

The TARDIS is empty. The Doctor has gone.

Jo Grant steps outside into the darkness and finds the frozen body of her friend, and the ship's log recorder. On it is attached a simple message - 'Use Me'.

As she explores this place, recording her every move, Jo discovers the horror that lies in the shadows.

But by then it is too late.

Written by Jonathan Morris, the story also marks the Doctor Who directing debut of one Louise Jameson, better known to fans as Leela, the savage companion she played opposite Tom Baker's Doctor.
