Glancing at the clock Sally realised that it had been nearly three hours since Greg had texted her about the car in the river.

She had been so engrossed in trying to find more evidence to support their case that she had shut out everything around her. Now she realised that it wasn't the passage of time that had dragged her from her research, but the sound of the lock on the front door being picked.

Thinking quickly she shut down the laptop, shoving it and her notepad in a cupboard under the sink, hidden behind the rubbish bin, before scooting through to the spare room looking for a likely place to hide.

The door suddenly crashed open, and the lackey who had followed Greg the previous day led a handful of thugs into the flat.

"The boss is certain she's here" Sally heard a voice saying as she crouched, still and silent in her hiding place.

"Someone was here recently," said another voice. "This mug is still warm."

Thinking quickly, Sally typed and saved a note on her mobile giving the whereabouts of the laptop and notes, hoping Greg would think to look for clues when he came home and found her gone.

Then, as the door of her hiding place rattled, she hid the phone and held her breath.
