A/N Sorry for the delay.
The quiet, calm atmosphere in the cab was broken by Jim's phone buzzing; he shifted Katy, who was still curled up against his chest and got his phone out of his pocket. The consulting criminal swore under his breath as he read,it was an automated message to say the laser trip system in Katy's bedroom had been set off. He was sure it wasn't Sebastian as he had been given the evening off, and Jim knew he would be trawling the bars looking for a bed to sleep in tonight.
"Is everything okay?" Katy asked, rubbing her eyes with the back of her hand and yawning slightly.
"Nothing I can't handle," Jim said, as he shifted to face her and placed his hands on her shoulders. "But I need you to stay calm. Sherlock found out sooner than we had hoped and he is waiting in the flat right now. Don't panic, I will be there for you, whatever happens."
Katy's chest tightened and she reflexively clenched the leather seat with her fist. Her gaze went down, as she tried to hide her fear from Jim. Even with the time to recuperate, she still didn't know if she was ready.
Beside her, Moriarty was becoming impatient. True, everything was going as he had plan, but she was still a wildcard in his immaculate timeline. He had to make sure she was prepared before they reached the flat, and more importantly, the little detective on his trail.
"Obviously this is a bit sooner than we had expected but we can still do this, I have called the police and they are going to be here as soon as possible. All I need you to do is hide the diamond in your room, in the safe box in the window sill Seb made, while I distract Sherlock."
Katy nodded her weapon in hand and ready as they pulled up to the flat.
Jim led her into the building, whispering comforting words quietly into her ear. He gave her a light push, directing her to go up the stairs and made his way into the kitchen, before entering the sitting room.
By the time Jim and Katy got back, Sherlock and John had moved into the sitting room. The sound of a turning key caused the shorter of the two to ready himself for action once more. The ex-army doctor tensed his arm, firearm in hand aimed at Moriarty once he had taken up a position in the doorway, looking as relaxed as normal, a mug of steaming hazelnut coffee in his hand.
"You took your time boys." Jim said a smirk playing across his lips as he leaned against the doorframe and placed his free hand in his trouser pocket.
"We wouldn't want to rush into anything now would we?" Sherlock retorted, trying to read the man; all he could get was that they were playing by his rules perfectly. "Where is the girl?"
"Very forward for not rushing into anything, you can have her though. All she ever does is cry anyway. Top of the stairs and turn left, it's the first door on the right."
"John," The detective nodded his head in the direction of the door. As John passed, the criminal stuck his arm out and stopped the smaller man. "You know what, I'll get her." He said with a bored sigh. "You two just sit tight and wait for me." John and Sherlock exchanged confused looks as Moriarty went to find his houseguest.
He made his way through the various defence mechanisms to find her cowering in the bath clutching the gun in a shaking hand. She visibly relaxed as she realised the person entering was her saviour and not one of the two villains downstairs. Jim noticed the irony somewhere in the back of his mind, but he didn't let it show.
"Have you hidden it yet?" He said as compassionately as he could, kneeling beside the bath, resting his elbows on the rim and rubbing the cowering girl's back gently.
"Yes." Katy sniffed, trying to stop anymore tears from rolling down her cheeks.
"C'mon hun, we have to keep Sherlock and John from finding the diamond." Jim said soothingly, helping her out of the bathtub before handing her the hazelnut coffee. She gulped some down before entering the bedroom.
With his hand now possessively on the small of Katy's back, Jim led her into the bedroom. To Katy's dismay the uninvited visitors had followed the psychopath up the stairs and were waiting for her in the bedroom. Katy was no doubt nervous but was managing to control it thanks to Jim's presence, and the firearm, out of sight from the visitors, in her hand behind her back.
"What are you doing here Sherlock? You know you won't find anything." Jim said from behind Katy. Sherlock gave him a quizzical look.
"You know what I came for, now let her go." The detective said gesturing towards Katy.
"I won't help you." Katy said to Sherlock who ignored her and continued his stony glare at the now grinning criminal.
"What has he told you then?" John says with an angry edge to his voice. "That we are the bad guys and he is the good guy?"
"He saved me when you kidnapped me. You are the ones pointing a gun in my face." John lowered the gun, putting it on the sofa behind him, and held his now empty hands up in a gesture of goodwill.
"We don't want to hurt you Katy, we want to help you." He said moving slowly towards her.
"NO, you want the diamond! I won't let you have it." Katy said; the panic rose in her chest and her head started to spin slightly.
"What diamond Katy?" John said in a soothing voice as he edged closer to her. Jim removed his hand from Katy's back and placed himself between the ex army doctor and Katy.
"Back off lapdog." Jim said squaring up to the doctor.
"You bastard." John yelled swinging at Moriarty. He hit him square in the jaw; the psychopath made a pained noise and fell to the ground smirking up at Sherlock as John kicked him repeatedly in the stomach.
"STOP IT!" Katy leapt forward, gun in hand and fired it at Sherlock. The bullet hit the unsuspecting detective in the chest; he slumped backwards into the wall, and slowly fell to the floor. Instinctively John stopped his assault on Moriarty.
"WHAT THE HELL HAVE YOU DONE!" He screamed as he ran to the motionless detective. Tears formed in Katy's eyes as she looked at what the army man had done to her hero, her head was pounding, and she felt physically sick as she sank to her knees beside him, stroking his hair with her thumb. He opened his eyes and weakly placed his hand on her cheek.
"I'm sorry hun." He whispered next to her ear as he injected her with an EpiPen, he rested her head gently on the floor before making his way out of the room. Sirens could be heard pulling up outside the residence, Moriarty stood painfully in the doorway, clutching his ribs and smirking at the mayhem he had caused, before texting his trusted sniper for a lift and leaving the scene through the back door as the police entered through the front.
DI Lestrade, Sergeant Donovan, and a team of officers entered the bedroom.
"Sally, get an ambulance here now!" Lestrade said taking control of the scene upon seeing Sherlock, slumped in a pool of blood, on the floor. "John, what happened?"
"Someone come and put pressure on the wound." John said, gesturing to one of the officers in the room before he rounded on Katy who was lying still on the floor, his anger blinded him, all he wanted to do was hurt this girl like she had hurt his friend. "It was her; she was working with him, Moriarty." Almost as if she had heard his words she started to convulse on the floor.
"What is wrong with her?" Lestrade said, as John came back to his senses.
"Damn. He's given her another dose." John held Katy's head steady as she fitted violently on the floor. When she had stopped he put her into the recovery position. The paramedics arrived shortly after, Sherlock was taken to St Bart's in London, and Katy was taken to a specialist psychiatric surgery outside the city.
