They arrived in an alley in central London, the three of them gasping for breath after being squeezed through the Time/Space vortex. No longer were they surrounded by the Future Kind instead they were surrounded by the hustle and bustle of London in the 21st century. It was time to find Professor Yana, or as the Doctor knew him, the Master.

As they walked down the street they discussed what their plan was. The Doctor knew that he only had to see the Master to know him, all Time Lords had the innate ability to know each other. That was then it hit Martha, she knew who the Master was. Harold Saxon, Prime Minister of Great Britain. Who had a wife.

Thus began the great hunt for information on what the Master's purpose was, to figure out his endgame. They went to Martha's apartment first as a base of operations from which to work.

"Home," Martha sighed out happily as she entered. The Doctor went straight to business.

"What have you got? Computer, laptop, anything. Jack, who are you phoning? You can't tell anyone we're here."

"Just some friends of mine, but there's no reply."

"Here you go. Any good?" Martha inquired as she fetched her laptop.

"I can show you the Saxon websites," Jack stated, "He's been around for ages."

"That's so weird though, It's the day after the election. That's only four days after I met you."

The Doctor hummed and said, "We went flying all around the universe while he was here all the time."

"You going to tell us who he is?"

"He's a Time Lord."

"What about the rest of it? I mean, who'd call himself the Master?"

"That's all you need to know," cut off the Doctor, "Come on, show me Harold Saxon."

Jack nodded and proceeded to call up the various webpages on Harold Saxon while Martha checked her voicemail, an overexcited Tish who had gotten a job, didn't really matter in the grand scheme of things. Just after that Harold Saxon made a speech and Martha's apartment blew up. Oh, how she loved travelling with the Doctor.

And so they went off the grid, trying to get away from the Master's eyes that were everywhere and everyone. They were declared terrorists after Martha had received a call from the Master and the Doctor had talked to him. They ran, they hid, the planned on a way to somehow gain the knowledge of the Master's plan. And then they had a visitor.

They had been talking about the Master and the Archangel network when Jack had stopped and abruptly stood up with his head cocked to one side. The Doctor followed soon after and they both gazed out into the night while Martha looked between them and the emptiness that she could see. There was a slight sound, almost like a cry for help and Jack took off like a rocket.

Martha watched as the Doctor let him go before scrambling around their makeshift campsite, organising boxes into an almost bed and covering it with various tarps they had found. He bundled up his own coat and placed it at one end before running off in the direction Jack had without so much as a glance at her.

She sat there, stunned at the sudden bursts of activity from her companions before hurriedly getting up to run after them. She didn't get very far as almost as soon as she had gotten up they appeared in the outer ring of the firelight. They were on either side of another person, male by the looks of it, and helping him towards their hidey hole.

The man seemed to be in bad shape as he stumbled in between the two travellers, almost falling several times even with their support. Martha's doctor brain kicked in and she ran forward to help only to arrive just as the man finally succumbed to unconsciousness. The three of them hurried him to the bed the Doctor had created and lay him down. Martha started checking him over as the Doctor hovered nearby and Jack knelt next to the new addition.

As she worked she felt her heart sinking, the man wasn't breathing and there was no pulse. He was ice cold even though it was a warm summer night. If she hadn't just seen him walking she would have said that he had been dead for a few days. She tried to perform CPR but Jack wouldn't let her, holding her away from the strange, probably dead, man.

Jack threw her into the Doctor's arms and he caught her, holding her just as tightly as Jack had. "Will he be okay?" the time lord asked Jack quietly.

Jack nodded, "He should be, eventually. His Constant has been thrown around and it's having an effect on him."

"What about you?"

A grimace, "It's not so bad, I only get an echo. He's getting the full brunt. Doctor, we need to stop the Master."

The Doctor nodded and Martha was confused. "Hold on! What are you talking about? Who is he? Why are you saying he's going to be alright when he's dead?"

"Because he's not dead, he's just in a lot of pain."

"But who is he? How do you know him and how do you know what's wrong with him?"

The Doctor and Jack both sighed and Jack knelt back down at the side of the bed, running his fingers through the stranger's hair. "We know him because he is like us and we are like him. I know what is wrong with him because he told me, his Constant is being hurt and so is he. He is Harry, Keeper and Guardian of Death."

"Th't's me," Harry groaned quietly as his eyes fluttered open and shut.

"Shh Harry, just rest. We'll get you better, you'll see." Harry just nodded slowly and curled up on himself, one hand reaching out to take Jack's.

"Stay," he murmured, "it's bett'r."

"I'll stay, Harry, for as long as I can."
