Tonight on Poldark from WGBH's Masterpiece: Ross makes his maiden speech in Parliament and finds some notoriety in London, where he also re-unites with a now adolescent Geoffrey Charles. In Cornwall, Demelza contends with a failing mine and fixing Drake’s broken heart. Dwight and Caroline welcome a baby daughter, Sarah, into the world but Dwight’s happiness is short lived as he makes a disturbing diagnosis. George hosts an extravagant party at Trenwith in the hope of buying his way back into Parliament and his new friend, the dangerous socialite Monk Adderley, makes the necessary introductions to set George on his way.

See it all play out tonight at 9pm on WGBH 2.
