Y Llyfrgell

A stylish, playful and enjoyably offbeat Welsh-language thriller, The Library Suicides (adapted from Fflur Dafydd's bestseller Y Llyfgell) stars Catrin Stewart (a cult figure from her role as Jenny in Doctor Who) as twin sister librarians Nan and Ana who plan revenge when their author mother commits suicide, with her final words suggesting her biographer murdered her. Set within the stately National Library of Wales, director Euros Lyn (who directed episodes of Doctor Who and Broadchurch) has made a gem of a thriller. (Edinburgh International Film Festival)
