Lucas was awoken from his dreamless sleep by the sound of his mobile phone ringing, god what time was it he thought, it only seemed he'd been in bed a few hours and as he glanced wearily at his watch his thoughts were confirmed as he registered the time as only being 3am.

He quickly noticed it was Harry who was calling him at that ungodly hour and answered the phone, after listening to Harry's demands Lucas hung up and put the mobile back down on the small table beside his bed and wondered why Harry wanted him in Thames House so early, and so obeying his boss Lucas got up, quickly showered & dressed himself and made his way into the capital.

As Lucas arrived on the grid he noticed that his fellow colleagues had also been called in and it became suddenly evident that they had already been briefed to the unfolding drama as they were all looking at him with worried expressions.

'Lucas, my office please.' called Harry as he stood in the doorway of his room.

Lucas wandered through, walked into Harry's office and closed the door behind him,

'Please take a seat.' Harry said, offering the chair opposite him.

As Lucas sat down he became increasingly agitated with what was going on and the look on Harry's face did nothing to allay his fears.

Harry spoke quietly, 'Lucas, I don't know how to tell you this but we have reason to believe your sister has been kidnapped.'

Lucas laughed and said 'But Harry .. I don't have a sister, you of all people should know that.'

But Lucas' smiled dropped when he realised Harry was being deadly serious.

On the desk sat a brown folder. Harry picked it up and handed it to Lucas saying 'Here, read this, I know this is a shock Lucas but everything will become clear after reading the file.'

Harry watched his section chief closely as he began to read the contents of the file and noticed the slight tremor in Lucas' hands become more and more prominent. As Lucas quickly read the pages, the words seemed to wash over him and he found it increasingly hard to register their meaning, it couldn't be true he thought, how could he have a sister and why did his parents never tell him of her.

More questions came crashing into his head and thoughts overloaded his mind and as he continued to read, he suddenly noticed a sentence highlighted in bold red ink. The colour drained from his face & he went deathly pale. Without warning Lucas got up throwing the file down on the desk he charged out of Harry's office and off the grid. He needed air, he felt he couldn't breathe and now running full pelt he made his way to the only place he knew where he could get the oxygen he needed….. The Rooftop.
