Cards on the Table (S01E05)

Furious about the gorge's destruction, Lady Maud approaches Dundridge, proposing a partnership to reveal Sir Giles as the blackmailer. However, Dundridge harbors a deep dislike for her, convinced she’s the reason for his downfall, and he declines her offer, vowing to ruin her home instead. That evening, Blott gets one of the construction workers heavily intoxicated, urging him to wreak havoc in the village to stir up anger against the roadworks. Meanwhile, Sir Giles, living with Mrs. Forthby, drugs her and attempts to set the hall on fire, fleeing into the grounds after a confrontation with his wife.
