Weeping Ra

When Angie comes home to see she has been offered a scholarship at a prestigious boarding school in Liverpool, she jumps at the chance to even visit. Clara accompanies her on her visit and after a tour of the school, Joy shows them something almost considered a monument at the school now, and Clara realises something isn't right. She calls The Doctor to help her. To Sibuna, this 'monument' is just the stone remains of Sophia, the alchemists daughter failed to complete the Pyramid of Ra, but is it something more?
