Sarah Lancashire has a sixth sense for choosing great dramas. Now she’s back with one of the most hyped dramas of the week. Featuring a solid supporting cast, including Mark Lewis Jones, Sidse Babbett Knudsen and Joanna Scanlan, this saga set in the fictional Welsh community of
Glyngolau is bound to grip from the first few minutes. It begins with an explosion on the construction site of a much-needed and soughtafter regeneration project. Several teenagers who have broken into the building site to make mischief are killed in the carnage, and one mother, Polly (Lancashire), directs her anger at the development’s project leader.
