Laura Ruth Sadler (25 December 1980 – 19 June 2003) was an English actress. She played pupil Judi Jeffreys in the children's school drama series Grange Hill, and nurse Sandy Harper in the BBC One hospital drama series Holby City for three years from 2000 until her death in 2003. Life and career Sadler was born in Ascot, Berkshire, and grew up in High Wycombe, Buckinghamshire. As a young girl she enrolled at the Jackie Palmer Stage School in High Wycombe, before joining the Sylvia Young Theatre School in London. She was spotted as a future talent at the age of six by Dustin Hoffman, who had seen her in a play and asked to meet her. Before joining the cast of Holby City, she had played Judi Jeffreys in the children's television series Grange Hill from 1997 to 1999. Her Grange Hill character died after slipping and falling out of a burning building. She also played the part of Skirty Marm in a BBC1 children's comedy, Belfry Witches. Skirty Marm and her friend Old Noshie (Lucy Davis) were teenage witches banished to Earth from Witch Island, settling in a sleepy village where they caused mischief. In 1996 she starred in the feature film Intimate Relations alongside Julie Walters, where she played a girl with a crush on her mother's adulterous lover. She joined the cast of Holby City, a spin-off series from the long-running BBC medical drama series Casualty, in the show's third series, playing the nurse Sandy Harper up until her death. Eight further Holby City episodes featuring Sadler as Sandy had already been filmed, and were aired as scheduled posthumously. BBC scriptwriters consulted Sadler's mother, Sonja Sadler, when devising the character's exit storyline. Mal Young said: "I went there thinking we were all going to be in tears and it turned into an unofficial storyline conference. I said we would find a way of explaining Laura's absence and her mum came up with an idea we all liked." Sandy's farewell episode, "A Friend in Need", revealed that the character had won £150,000 in the lottery, and left for Australia to follow former love interest Danny Shaughnessy. After discovering various amounts of money she had left behind for her friends at Holby City Hospital, the characters gathered together in the hospital bar at the end of the episode, and raised a toast "To the one and only Sandy!"
