With Lucas back within MI5, he reveals that the Russians interrogated him about Operation Sugar Horse, the most secret ongoing spy operation MI5 has ever had. It appears that MI5 has a very high-level mole, so Harry seeks out his mentor, The Spycatcher, to help find the mole. Meanwhile, Ben is undercover with an Al-Qaeda cell that is planning to bomb London when what looks like a dry run unexpectedly turns live.
