Chapter 45.

'When you say not good, how bad are we talking?' asked Jamie.

'We're talking very bad,' said Jack running a hand through his hair.

'Who are they?'

'They are part of an organisation of intergalactic assassins. Highly trained and lethal. They're nicknamed the Sirens, because they're all women, and meeting them generally ends in death.'

'Great,' Molly said sarcastically.

'I take it you've had dealings with them before?' asked Ianto.

'Let's just say that I was not always the fine upstanding citizen I am now,' answered Jack.

'Not sure I'd describe you as that now,' smirked Ianto.

'Really, wait till later and I'll show…'

'Ok back to the matter in hand.' said Jamie cutting off Jack's comment.

'Yes the Sirens. Thing is as far as I know they have no psychic abilities, so it's not them influencing you're dream.'

'Plus highly trained assassins are not exactly going to let you know they are coming,' commented Ianto.

Then something inside Molly clicked like a light bulb being turned on. 'The voice. The voice in my dream said "You have to help me". It's got to be whoever they are after that's getting to my dreams, their asking for help.'

'If that's true, then we need to find out who they are.' said Jamie.

'So that narrows it down to a city full of people,' muttered Ianto.

'The voice sounded female,' Molly interjected trying to sound helpful.

'I doubt it's someone from Earth. No one from here would know about the Sirens, far too advanced. Whoever it is must have escaped from them using the Rift, ended up on Earth.'

'We haven't had any significant Rift activity in days though,' said Jamie.

'Sirens could travel through the Rift and then back again without us ever knowing. Extremely sneaky. When did you're dreams start?' asked Jack.

'It's been five nights, although I don't remember the first four.' said Molly.

'Go back and look at any Rift activity for five days ago, and we'll see what we can match up. We'll have to give the police a description of them, the last thing we want is them engaging them.'

'How do we know the person in Molly's dream isn't as bad as those after them?' commented Jamie.

'We don't,' answered Jack, 'People send others to kill for them for a whole host of reasons, money, power, revenge. That isn't our concern though, we just need to find them and send them on their way.'

At this point the alarm on the door sounded and Gwen walked in. She looked at them all gathered around the couch and said. 'Did I miss something?'

'I'll fill you in,' said Ianto getting up and moving over to her. He could use Gwen's help with liaising with the police.

Molly went to her computer and bought up the logs for five days previous. 'Here it is, Gwen and I went out and picked up a device that had fallen through the Rift and landed in the grounds of the castle. We determined that it wasn't dangerous, so I put it on my to do list.'

'I remember you showing me something, let me see it again.' said Jack.

Molly reached behind her desk to a table that had various gadgets on it that she had yet to process and research. She handed Jack what looked like a small square brown box. It had buttons on one side and what looked like a key hole on the front. Jack took it and looked at it carefully, his brow creasing in concentration.

'This is used for travelling. I should have realised, but I didn't really take any notice of it before.'

'Time travelling?' enquired Molly.

'No, travel between planets. It's more like a teleport. On planets more advanced than this one, they use them to travel to other nearby planets just as we would get on a plane to fly abroad. I can think of a few systems that use this kind of technology, but it's not supposed to be used for travelling to somewhere as far as Earth. Who ever this belongs to must have got caught up in the Rift.'

'And got separated from this when they landed.' finished Molly.

'Seems like it.' He turned the box over and over in his hands.

'So in theory, if we got this back to it's owner, they could use it to travel back through the Rift and away from here.'

'In theory, it depends how well it's still working, and without the key, we'll never know.'

'I'll see if I can get any residual energy off it, gives us something to trace.'

Jack left her to it and headed back up to his office. He hadn't been sat down long when Ianto entered, two mugs of coffee in hand.

'I've given some to the others too, I have a feeling it's going to be the only thing keeping Molly awake by the end of the day.' He passed Jack's mug over to him, their fingers brushing slightly.

'So,' started Ianto. 'Are you going to tell me why these assassins were after you?'

Jack grinned, 'Let's just say I took advantage of the wrong person and they weren't happy to say the least.'

'How did you get away from them?'

'By using charm and cunning,' answered Jack. Ianto just raised an eyebrow at him. 'Come on, I have to keep some mystery, and you know you love it when I'm all mysterious.' Jack leaned over the desk, towards Ianto, but was interrupted by Gwen's voice calling up to the office.

'Jack.'

Jack sighed getting up from his desk and walking out of the office, Ianto by his side. 'What is it Gwen?'

'I've had some reports coming in of two women matching the description of those in Molly's dream. They were spotted by the car park on Greyfriars Road. Police are directing people and traffic away from the area.'

'That's not far from the castle where we found that device,' said Molly.

'Right, everybody to the SUV. Make sure you have your weapons fully loaded. Take no unnecessary risks, as you should be in no doubt, if they feel threatened they will kill you without even blinking.'

'There's a comforting thought,' mumbled Jamie. 'You going to be ok.' He asked Molly.

'Yeah, I want to get out there and do something. See what we can find out.' Molly answered.

The team gathered up their weapons, and went down to the car park. They climbed in the SUV and sped off.
