As the three-part series continues, Verloc decamps to Michaelis’ cottage in Kent as he puts his plan to bomb the Greenwich Observatory into action. He’s taken an unsuspecting Stevie with him, so as Winnie minds the shop in London, she mistakenly believes her husband is finally bonding with her beloved brother. It’s not long, however, before Michaelis becomes suspicious of Verloc and, as he does so, the Professor (Ian Hart) goes to dramatic lengths to taunt Chief Inspector Heat (Stephen Graham), telling him that a bombing is imminent, but he refuses to say where it will be. Meanwhile, Ossipon takes full advantage of Verloc’s absence and makes advances to Winnie.
