With Tom being Salters official confidante, Zoe calls
him in. Harry admits to Tom that Salter is on a joint secret operation between MI5 and 6,
in an effort to catch Istvan Vogel, the leader of an extreme anarchist group. MI6 suspect
Vogel of planning to disrupt President Bushs imminent visit to the UK.
As Tom struggles to remain calm with the exasperating Jools
Siviter of MI6, an increasingly tangled web yields unexpected news: Salter has fallen for
one of Vogels followers, Andrea.
A showdown sees Tom order Salter off the case, but Salter
flees. Unsure now whose side he is on, Tom and his team try desperately to find him.
Things become further muddied when Harry, keen to regain control, commands Tessa contact
one of her covert agents who, its thought, is undercover with a related anarchist
group. Zoe goes to meet the agent, only to find Tessa waiting. The corrupt Tessa has been
running phantom agents and pocketing their pay. She hands Zoe £10,000, in return for her
silence.
Whilst MI5 search for him, Salter, Andrea and other members
of Vogels group break into a university campus, where Salter hacks into a computer.
Security catches them in the act and, although the others escape, Salter is caught and
hauled back to Harry and Siviter. Tom uses all the tricks he learnt from Salter, and gets
him to admit to betrayal but beyond this obvious admission, the secret services are still
in the dark - and Bushs visit is getting closer. What was he doing in the
university? Before Tom can attempt further interrogation, Salter takes his own life and
keeps his secret to himself.
