"Gerry?" Sandra called as she and Jack returned to the office, only to receive no replies. "I'm putting the kettle on, wanna cuppa Jack?"

"Yeah, why not? I'm just going to write up our findings on the board while we wait for Gerry to get back."

"Do you think I should make him a cup?" Sandra asked as she poured water from the kettle into two cups and, when Jack didn't respond, into a third.

"Guv'nor, I'm back." Gerry called as he walked in the office door and chucked his car keys down on the table.

"Just in time, your coffee's getting cold." Sandra told him, not even bothering to turn her head, as she sat comfortably on the sofa drinking her drink and staring at the whiteboard that was home to the details of their current case.

"Ah, thanks Guv'" Gerry said as he picked his coffee up and sat beside Sandra.

"So what did you get from the girlfriend?" Sandra asked curiously, only now looking over at him.

"Not my type but she is a looker so I can see why Ronald would want her, she's with a girl now though."

"I meant about the case."

"Oh, well she last saw before 9am on the day he was killed, her dad had just found out but Ronald's family didn't know. She also said something about Ronald saying that someone was after him."

"Ah, well, we'll need to do some digging on that. I think it's time we spoke to the wife..." Sandra began as she put down her mug and picked up the case files in search of Ronald's wife's name. "A Nancy Truman, now Front."

"It might be a bit late to go and see her." Jack pointed out as the small hand on the clock reached the four.

"Fine, we'll do that tomorrow. In the meantime I'd like some work done on the Rosenberg's, Stalin, Khrushchev and Berlin in the 50s." Sandra asked as she picked her mug back up and headed for her office.

"Why?!" Gerry asked as he stared at her with a look that was meant to say 'have you lost your mind?'.

"Well you asked why Ronald moved to the UK, Willie came over a month after Ronald in 1957, they both came from the same city and both came to be closer to the action in Eastern Europe." Sandra Added.

"Okay."

"We'll come together in an hour and see what we've got." Sandra called from her office as she typed Stalin into Google.

"1957 was still relatively early days with in the Cold War, by this time the USSR had taken over the majority of Eastern Europe, Truman had announced the Truman Doctrine 1947 which meant the USA would offer military help to any country fighting communism and then the Marshall Plan was announced to give money to countries to stop them ending up Communist." Jack began as he took over the job of being the font of knowledge in Brian's absence. "In 1949 Stalin blockaded West Berlin in hope of taking it back over, as it was a capitalist city surrounded by a sea of communism, it lasted 10 months before Stalin took it down. In 1949 NATO was formed and in response to that the Soviet Union announced the Warsaw Pact, the same year China became a Communist country."

"Stalin died in '53 didn't he?" Gerry asked.

"Yeah he did and as Willie said, he was replaced by a man called Nikita Khrushchev who announced Peaceful Co-existence and De-Stalinisation. From what I can find the first idea meant that Communism and capitalism could live side by side peacefully and that war should be avoided and the second meant that living standards would improve and publicly criticized Stalin." Sandra told the other two.

"All I could find was that there was an uprising in Hungary in 1956, although I don't think that's relevant and that the Rosenberg's were important American scientists who were accused of giving the secret of the atomic bomb to the Russians and they were executed for it." Gerry added. "Is any of this Cold War stuff really relevant though?"

"We don't know yet Gerry but if it is then we have some background knowledge now."
