I've had this idea for a while ever since watching the third series and I know there are brilliant stories out there already that look into a possible take on the fourth series but I just couldn't help myself, I wanted to add my own little tale too! I've already written quite a lot of this story and I'm editing it as I go. I really hope you enjoy it and I'll post the next chapter very soon!

Disclaimer: I do not own these characters.

Chapter 1

Darkness and a dull throb in her temple greeted Molly Hooper as she drifted back into consciousness. Disoriented and in pain she waited for her eyes to adjust to the surrounding blackness. After a few moments Molly squinted and made out the high cement walls that enclosed her. There was a metal door with a small slot at the bottom yet the door had no handle. The room she was in was small and Molly felt a little claustrophobic.

Something trickled down her cheek, causing her skin to itch and Molly went to bring a hand up to wipe whatever it was away, only to discover that she was strapped by her wrists and ankles to a metal chair. Her heart started to race as she tugged at her restraints, panic and confusion bubbling up inside her. She thought frantically over how she had come to be there but was coming up blank. Her wrists were starting to hurt with her pulling so she stopped. Breathing heavily Molly struggled to calm her racing heart but she could do nothing to stop the frightened tears that gathered in her eyes.

Heart pounding, Molly struggled not to lose the battle against an impending panic attack when the metal screech of a heavy door sounded. Yelping and swinging her head around to face the door she watched as a short, thin figure stood in the doorway. It was difficult to make out who it was as they were silhouetted by the bright light behind them but Molly felt the breath catch in her throat in sudden terror. Lights suddenly burst into life in Molly's cell and she flinched as the brightness seared her eyes. She closed them tightly for a moment, her eyelids fluttering as her eyes adjusted to light. As soon as she saw who it was, however, she wished she had never opened them.

"Did you miss me, love?"

Molly watched as Jim, her ex boyfriend, James Moriarty, Richard Brook, the supposed dead Consulting Criminal extraordinaire, stepped into her cell. Realisation struck Molly like a sledgehammer as the memory of being in her sitting room and seeing Jim's face on her television set flooded her mind. Her memory was still a little fuzzy on what happened after seeing the broadcast and she shook her head firmly to try and dispel the fog that surrounded the memory.

Her focus went back to the man before her. He wore a tailored, expensive suit, his dark hair slicked back, and a smirk playing about his thin lips as his dark, emotionless eyes gazed at her intently. Fear spread like wild fire through Molly's chest as Moriarty moved closer, his eyes sliding over her bound form and Molly shivered under his unpleasant stare. She bit her lip harshly to hold in a whimper as he stood before her, flinching when he trailed his cool fingertips against her cheek. His cold fingers suddenly gripped her chin tightly, tugging her head up to look at him.

"I said, did you miss me?" Moriarty repeated, his voice shrill and harsh and Molly couldn't hold in the cry that burst from her lips when his nails bit into the curve of her jaw. He leant in towards her, his hot breath washing over her face as he suddenly grinned.

"You didn't think I wouldn't find out that you helped him, did you, love?" Moriarty whispered, his face close to hers and Molly was unable to look away from his manic expression. "Sherly thought he was so clever, didn't he? Well, we both know who's clever, don't we, Miss Molly?" Molly closed her eyes tightly when he leant forward and nipped at her cheek, a tear escaping her clenched eyes. Her breath hitched with a suppressed sob as Moriarty moved back, a low chuckle escaping him.

"We're going to be spending a lovely time together, Molls. Just like the old days, huh?" He said with a soft laugh, chucking her under the chin before he turned smartly on his heel and left the cell, the heavy metal door slamming shut with a loud thunk. Molly sat there for a long moment in shock, until the tears that had been pricking her eyes finally spilled over and she broke down, sobbing quietly in the cold, suppressing darkness.
