"Matthew Rhys will star as Jasper, who becomes obsessed with 17-year-old Rosa Bud (Tamzin Merchant). A secret opium-addict, Jasper develops a murderous hatred of Bud’s betrothed, his nephew Edwin Drood (Freddie Fox). As the tale unfolds, the audience is left wondering how far he will go to attain the object of his desire."
"The tragedy of the erotically obsessed cathedral choirmaster, John Jasper, throbs with sexual menace, murder and opium addiction. But alongside his story runs a brilliant small-town social comedy which is often laugh-out-loud funny. After all, this is Dickens, the great emotional extremist, and master of the rollercoaster ride. It’s just the most enormous fun.”
