A humble shopkeeper in Victorian London is secretly acting as a spy for the Russian government. He plans to arrange a bombing that will be blamed on the anarchists he is spying on - but needs to find an accomplice.

Heat pursues the Professor in order to prevent him detonating a bomb on an omnibus, after which he is arrested. Meanwhile Verloc's plan goes horribly wrong as the bomb goes off too soon, killing Stevie with Verloc getting no support from Vladimir and the label found in Stevie's coat leading Heat to Verloc's shop. Ossipon flirts with Winnie, who rejects his advances, believing her husband's lie that Stevie is safe in the country until Heat explains her brother's fate to her.

While Chief Inspector Heat struggles to makes sense of the plot behind the Greenwich bomb, Winnie is devastated by the news of Verloc's role in the outrage.
