THE BODYGUARD

Despite their affair, Julia stands for everything Sgt David Budd hates.

The former soldier, played by Richard Madden, has been left with PTSD after serving in Helmand, and is distrusting of politicians, especially those who voted in favour of the conflict.

Torn between his beliefs and his duty to protect, Budd has been forced to decide where his loyalties lie.

Combine that with the fact he was asked to spy on his lover by his Met boss, Anne Sampson, and that he saw his Army pal Andy Apsted, played by Tom Brooke, attempt to kill Julia, it’s no wonder he isn’t stable.

Matt says any credible suspect will have means, motive and opportunity.

Budd has all three. But Matt thinks the real twist will be that Budd was meant to be the target after all.

“Budd is the key,” he says. “He was very close to being killed on the train. Then if we move on to the bomb scene when Julia is killed, a device is triggered by someone stepping onto the bomb – a place Budd was very likely to go.” According to bodyguard protocol, Budd should have been there – not in front of the stage. “He’s been the target,” speculates Matt. But even if he wasn’t Matt still thinks he’s a credible suspect. He could want revenge for his friend Andy killing himself, or blame Julia for the scars he bears. He also met an ex-military contact to buy a Romanian military rifle of the kind Andy used in his assassination attempt. He could also have gone from hero to killer because Julia failed to tell him his children’s school was a terrorism target. Or could Budd be working with the terrorists? Matt says any of the theories are possible. MURDERER MARK: 7/10
