WARNING: Major spoilers for episode three ahead.

May 3, 2000: Jim and Jane arrive at ‘Camp Zeist’, the specially-made courtroom at an American Army base for the beginning of the trial. News reports see it declared the ‘trial of the century’. Members of the support group speak to reporters outside, eager to see justice be done. Once inside, Jim greets other members, and is informed there’s 1,000 prosecution witnesses to get through. Jim vows to be there every day – and he’s warned it could take at least six months.

Murray Guthrie is among the press in attendance in the gallery as the trial commences, as is Megrahi’s wife and children. Both Megrahi and Fhimah plead not guilty to the crime.

Among the witnesses are several members of the Lockerbie community who witnessed the explosion, explaining the devastation they saw and how it affected the small town.

At their apartment in Utrecht, things are quiet between Jim and Jane as she struggles to digest what she’d heard that day. She admits her regrets at not visiting Flora’s body in the ice rink. Jim admits that he thinks Megrahi and Fhimah committed the crimes, and they’ll be witnesses to justice at last. Jane later flies home, leaving Jim in Utrecht, and he promptly builds a new wall of evidence.

Over time, the amount of people in the gallery dwindles, and Guthrie joins Jim. Evidence about a piece of circuit board used in the bomb is presented, with the argument that it was made by a company called Mebo in Zurich. It was found lodged in a shirt. Jim comments to Jane how incredible it was for this one small piece of plastic was found amid millions of pieces of debris, and now they need to prove that Mebo sold this board to the Libyan intelligence agency.

The next day, the business owner, Mr Bollier, identifies Megrahi as a man he recognised and did business with, explaining that he works for a company in the same building that works in. He confirms he sold 20 timers to Libyans, but that his dealings were with friends of Megrahi, not directly, arguing Megrahi was a higher manager. Upon seeing the circuit board fragment, Mr Bollier causes a stir by saying that it was not the same piece he was previously shown and that it was a counterfeit that did not come from him, but under pressure folds and agrees with everything the prosecution tells him.

Tony Gauchi, the second key witness, is a Maltese clothes owner whose material was found wrapped around the bomb. He states that men from Libya come to Malta ‘for business and pleasure’. When he’s asked to identify who bought the clothes from him, he points at Megrahi, stating he told him he didn’t care about the clothes ‘because they weren’t for him’.

Outside, Jim and Guthrie talk about the Department of Justice being present despite it not being in their jurisdiction, but Jim brushes it off. When examined by the defence, Gauchi is pressured about the number of interviews he gave to Scottish police, who argue that he ‘had trouble’ identifying Megrahi prior to begin with. Gauchi gave 18 interviews and 19 statements to the police during their investigation, during which he changes his description of the purchaser in question significantly, and doesn’t mention a shirt until statement 17.

Guthrie says police kept going back to him until they got the answer he wanted, and after some digging himself, believes there may be an Iranian or Palestinian connection. Jim notes that, even discounting Gauci, there is still a significant amount stacked against Megrahi and Fhimah.

Four months into the trial, and Jane is struggling at home. She ignores Jim’s calls and instead, spends the evening driving to Lockerbie. She visits a woman, who takes her to where Flora’s body was found. Jane breaks down in tears, apologising to Flora, later visiting her grave.

Back at Camp Zeist, a third witness - Majid Giaka, a Libyan informant for the CIA - is interviewed under strict anonymity, with his voice distorted and his identity hidden. He previously worked with Fhimah and Megrahi at the airport in 1986, before working at the Libyan intelligence Service shortly after the US attack on Tripoli. He claims that Fhimah showed him 10kg of TNT in his office, which Megrahi had snuck into the airport.

He claims he saw Megrahi and Fhimah at baggage claim at Malta airport, picking up a suitcase and taking it through security. Defence pushes him about why he requested the CIA give him money to emigrate, but the CIA declined, with a letter stating that he wasn’t providing them with the information they needed, and if he didn’t improve by 1990, then his employ would be terminated. Giaka smiles, and is caught looking at two American men from the Department of Justice on the prosecution bench. He then reveals he knows and is on first name terms one of them, throwing his whole testimony into question.

Jim later confronts the man in the bathroom, saying there should be a mistrial for what they did and that it should be a fair trial. The DOJ officer argues they have “one shot” and questions why Jim would “want to walk away with nothing”.

The next day, a baggage handler from Heathrow, John Bedford, testifies that, after a break from his work, he returned to find two new suitcases in the container that he didn’t put there. He didn’t see who put them there, and argues anyone who was airside could have put them. These suitcases appeared before the Malta > Frankfurt flight arrived.

That evening, Jim and Guthrie theorise that there was no bomb on the Malta > Frankfurt flight, which would remove the entire basis of the trial and completely collapse the case.

The next day, a weapons expert tries to dispute claims that the Palestinians were involved, arguing their type of device, a so-called “ice cube timer” that’s triggered when a plane rises in altitude, dropping air pressure. It would’ve exploded 35-45minutes into a flight.

The expert notes that it would have exploded on its first flight, Malta to Frankfurt, if this were the case, not on its third from Heathrow to JFK. Therefore the argument that the Libyans used this equipment couldn’t be accurate. Jim realises that Pan Am 103 exploded 38 minutes into the flight, and therefore the ice cube timer theory would be correct if the suitcase was put on the flight at Heathrow – just like the ones the handler testified appeared out of nowhere.

When no one flags this as a possibility, Jim disrupts the trial, banging on the window of the gallery, holding a sign stating ‘103 exploded after 38 minutes’. Guthrie begs him to sit down, and his alert is dismissed as an ‘unfortunate interruption’.

Jim now sufficiently doubts Megrahi and Fhimah’s guilt, and together with Guthrie, they start going through evidence again from scratch.

When Jane comes to visit, she finds Jim on the floor of his flat surrounded by papers, and he admits that he thinks Megrahi and Fhimah were framed, and are innocent.

The PFLP-GC is the Popular Front for the Liberation of Palestine – General Command, a Syrian-based militant Palestinian nationalist organisation and part of the Palestinian Liberation Organisation (PLO) whose aim upon its founding was to establish an Arab state over the entire territory of the former Mandatory Palestine.

It is recognised as a terrorist organisation in multiple countries, including the United Kingdom and the United States.

They were the first group suspected of committing the Lockerbie bombing due to a previous threat against the US before the attack took place.

Members of the PFLP-GC had been caught preparing bombs in radio cassette players in Frankfurt, West Germany, three months before the event – devices similar to that used by those who committed the attack on Pan Am 103.

While they were later ruled out of being possibly responsible, suspicion has continued that they were in some way connected to the attack. Conspiracy theorists claim Mohammed Abu Talb, a Palestinian terrorist who planted bombs in Amsterdam and Copenhagen in 1985, carried out the attack. Talb is mentioned in the series during Gauchi’s testimony as the possible “6ft 1in man in his 60s” he claimed to have served in his initial interviews.
