3. Junaid, a youth worker, took a party of teenagers to the Surrey Hills during the October half-term holiday for a day's nature ramble. Even though Junaid assured the teenagers' parents they would return home immediately after lunch, he decided to take the party to visit an ancient Roman Tower. Although the visit to the Tower only took 15 minutes, when the party came back downhill a thick mist suddenly enveloped the hills. The temperature dropped rapidly and visibility was very poor but it was not until dusk began to fall that the teenagers became scared. Junaid had forgotten to bring with him his map and compass, and the group became hopelessly lost. Some of the teenagers had mobile phones but it was impossible to obtain a signal on the hill so they could not raise the alarm. After rambling aimlessly for some considerable time, they took shelter in a clearing on the hill to wait for the rescue services. Maggie, one of the older teenagers, disobeyed Junaid's instructions to remain with the group and decided to find her own way home. Ten minutes after she left, they heard a loud scream. Maggie had missed her footing and fallen over the edge of a cliff. She suffered a broken leg. Meanwhile, when Junaid failed to return home at the expected time, his wife contacted the police and a local search party set off to find the group. As they were searching. Mihnea, a member of the rescue party heard Maggie crying. He decided not to wait for the other members of the rescue team to join him and he tried to lift Maggie single-handedly. They both slipped and Maggie suffered facial injuries as a result of the second fall. On arrival at the local hospital Maggie was informed that her face would be severely scarred as a result of the injuries. Liam, the consultant plastic surgeon, advised her of a silicone treatment that would help to eliminate some of the scarring. When Maggie asked if the treatment had any associated risks, Liam said: "Well, nothing is ever 100 per cent safe but you need have no worries about this treatment. I have used the silicone treatment on many of my patients and it has always been completely successful.' Although Liam was not negligent in carrying out the treatment, Maggie has suffered an allergic reaction to the silicone which has left her face permanently scarred. On her recent 18th birthday Maggie had signed a contract to be the 'face' of an international cosmetic organisation and was predicted to earn more than $1 million in her first year. Maggie got very depressed with the fact that she had a permanent scar and she might not be able to pursue her dream of being a super model. Her mental health gradually deteriorated and she suffered from psychosis and hallucination. 6 years after the operation, she took her own life.
