AIRSTRIP – OUTSIDE LONDON

As the car pulled away from the airstrip and sped back to London, Sherlock rested his head against the backseat and took a steadying breathe in an attempt to calm his overstimulated mind. He needed to remain focussed on the Moriarty Situation. Except that something, or more accurately someone was determined to make their presence felt.

'That was a calculated risk wasn't it," the voice whispered.

Sherlock shook his head violently, trying to dislodge the unwanted and unwelcome intrusion.

'Surely you knew you couldn't silence me forever?' the voice continued. 'But now that I'm back, oh the terrible deeds I have planned Sherlock, just you wait and see.'

Through the rear view mirror John and Mary noted the sudden clenching of Sherlock's jaw and hands. But they paid it no mind, confident that it was merely an after effect of the overdose.

How could they know what had been unleashed? Nor the devastating consequences that were likely to follow because of it.
