Shirley Brent, 23, is a Staff Nurse at St. Angela's. She did her training at another hospital; but failed her finals and moved to St. Angela's rather than face the humiliation of re-sitting them at her old hospital. She's totally absorbed in nursing, unintentionally annoying fellow staff by her seriousness. She's a rather plain, lonely person living on her own in a bed-sit, never having had much of a social life. In fact she's just the sort of girl who will quickly rise in the profession, no doubt a future matron.
