Hopefully this will be interactive! At the end of each chapter there shall be a challenge. PM me with your answer and your character's name. Obviously you can search for the answers but that makes it less fun (and is kinda cheating). You have the power to change the storyline- do you accept your challenge?

'So... Are you going to tell me or am I going to have to beat it out of you?' Cal playfully punched Ethan in the arm.

'What? I don't know what you mean!' Ethan tried to play the naïve idiot but the flushed colour of his cheeks gave him away.

Cal raised an eyebrow 'I'm pretty sure you do. Go on. Spill.' He stared into Ethan's eyes. Ethan squirmed and tried to divert himself from his brother's gaze without success.

'Fine! Her name's Finn. Finlay Trevders. She's a school nurse. She's 28 and lives not that far from us.'

'And...' Cal prompted.

'I think she's great.'

'And...'

'What?'

'Do I have to spell it out for you? Where did you two meet?'

'At the gym.'

'Since when do you go to the gym?!'

'Since when do you ask so many question?'

'Wait- on Saturday at like 8.30 you said you were going out and then didn't get back for a while later- where did you go?'

'A TRX session.'

'A what?'

'An hour of pure torture.'

'So is this your new craze?'

'Not really a craze, dear brother, more like an obligation to my body.'

'Whatever you say, "dear brother".' Cal once again punched Ethan and wandered off to collect his next patient.

'So I hear you're off to paradise?'

'Excuse me?'

'America?'

'Oh right yeah. Caleb and I are off on a little holiday.'

'Little? I heard you'd taken three weeks off!'

'Yeah... Hey haven't you got anything better to do Robyn?'

'Nope!'

'Robyn, assistance in cubical four please!' Tess called from the cubical, as if on cue. Robyn groaned and pulled herself away from where she was standing with Ethan. Ethan was relieved that she was finally gone, yes three weeks was a long time to be away, especially with his brother but he had earned it. The trip was scheduled before Christmas but the trash meant that they had had to reschedule their plans. Ethan had kept his days off few and far between, he had also made sure that Cal had kept his days off to a minimum. They wanted a break. They needed a break.

Ethan sighed as he drew himself away from his thoughts.

'Mr Dewen please.' Soon the old man was by his side being led to a cubicle, the first of many that slipped by without a second thought.

'Ready?'

'Yes. Finally.'

'Thank you!' Cal had been waiting in the staffroom for nearly an hour after their shift had ended because of Ethan's troublesome patient. He was desperate to get home and finish his packing, or even start it. The flight wasn't until 3 am the following morning so he had plenty of time to stuff his belongings into a bag.

'Please tell me you didn't leave it all to the last minute to pack.'

'Well I would, but that would mean lying to you.'

Cal pulled into the driveway and climbed out of the car, grabbing their bags from the backseat.

'You pack- I'll cook.'

'Deal.'

Cal ran up the stairs while Ethan made his way into the kitchen to start dinner. Dinner was quick and simple but delicious. Within minutes of sitting down they had already finished. Only then did they realise quite how hungry they had been.

'So- are you ready yet?'

'Yup.'

'Alarm set?'

'What do you think?' Ethan rolled his eyes 'I'll set it in the morning'

'Sure... I'm going to bed. I'll see you in the morning.'

'Morning?! What is this strange concept?'

'Ha. Ha. Seriously. I'm going to sleep. Goodnight Cal.'

'Night Ethan.'

Cal listened as Ethan walked around upstairs, he heard him opening draws, flushing the toilet and brushing his teeth. He waited until it had quietened upstairs before he made his own way upstairs. He got ready for bed before setting his alarm and sinking into the duvet.

The alarm blared its song. Cal rolled over to hit the snooze button but couldn't find the alarm clock.

'Morning Caleb.'

Cal swore.

'What the hell was that for?'

'Just trying to get you up.' Ethan smiled sweetly.

'Yeah? Well you scared the life out of me!'

'Come on. We need to check in in two hours. We need to leave in an hour. You need to get up.'

Obediently Cal got out of bed and rooted around in his draw for some clothes.

'You can go now.' And Ethan left.

The airport was bustling, despite the time. Cal slept the entire journey there but Ethan was restless. He was desperate to start his holiday, to feel the warm sun on his face. The boys stepped out of the airport and began making their way towards the shuttle bus, which would take them to their rental car company. They stepped off the bus into the sweltering heat and started to walk towards a modern looking building, surrounded by cars, glimmering in the sunlight.

Ethan felt something pressed against his mouth and nose, he felt the warm breath down his neck and he watched as the world blurred before his eyes.

Ethan was trapped. His wrists were bound to something cold and solid. He squirmed and tried to free himself.

'Don't bother. I've been trying for ages and still no luck.' An American accent cut through the air.

The voice made Ethan freeze. He was slowly becoming aware of his surroundings. He took in the large metal box, the two vents in the ceiling, the shirtless man sat opposite him.

'Who are you?'

'CSI Greg Sanders, with the Las Vagas Police Department in the Crime Lab:'

'And why aren't you wearing a shirt?'

'They strip you of anything that identifies who you are.' Ethan looked confused, prompting Greg to continue. 'I was on my way to a crime scene from my lab, I was wearing uniform- my t-shirt and vest identify me as LVPD, CSI, forensics and Sanders. So, they've left me shirtless.'

'Right. Why hasn't Cal woken up and who's the woman?' Ethan nodded to where a young woman with long, frizzy black hair lay, curled up in a ball.

'It's the effects of the gas. He'll wake up soon. And that-' he nodded to where she lay 'is someone who will want to introduce herself. Trust me. Anyway- you never said who you were.'

'Oh right- sorry. I'm Dr Ethan Hardy, Registrar at Holby City Hospital in the Emergency Department. That's my brother. Dr Caleb Knight. We also work together.'

'You're British aren't you?'

'Yeah. Came over here for a relaxing holiday. So far it's going great!'

Slowly Cal sat up, followed by the woman.

'So Cal. We're stuck here, it seems.'

'Where is here?'

'Good question.' Greg answered.

An uncomfortable silence began to settle in the room. Eventually the woman spoke.

'I have no idea who you two are but I'm Detective Jane Rizzoli, Boston Police, Homicide.'

'Dr Caleb Knight and Dr Ethan Hardy. Holby Emergency Department.'

'England?'

'Yep.'

A loud voice boomed over the speaker system inside the room.

'Welcome. We're going to play a little game. It's simple really. You are asked a question. You answer the question. You are provided with food, water and a first aid kit. You sleep. And then it repeats. Simple. Oh, but every wrong answer means one more bullet fired- either into you or into someone you love. Good luck.'

'Well. That sounds fun.' Three faces turned and stared into Greg's. Clearly the sarcasm wasn't appreciated in this situation.

Gas began seeping into the room, hissing through the vents in the ceiling.

Ethan woke up alone in another room. The voice boomed over the speaker system.

'Question one is an easy one. Good luck: If a bat and a ball together cost £1.10, and the bat costs exactly £1 more than the ball. How much does the ball cost?'
