Sky High by Guy Meredith

It's the early hours of a new day and in a tall London office block, a woman is busy working.

She thinks she is alone, but then she hears the lift doors open.

As we listen to the action, the clock is ticking away in real-time.

Emma needs to unravel a mystery code in the computer and she hasn't got much time.

Will Mark agree to help her or is he more interested in revenge? He used to work there and is keen to settle a score or two.

Can Emma trust him? Will she find the code in time? The tension is mounting ...

The clock is ticking away in this cat and mouse game of twists, turns and subterfuge.

Written by Guy Meredith.
