Peter KelderCarolinda Witt is an award-winning author who lives in Sydney. She keeps herself fit and healthy by practicing The Five Tibetan Rites, which she began 21 years ago. She has since taught the Rites to over 50,000 people all over the world through her boks, online training course, DVD, and workshops - and attributes them to her youthful appearance and energetic outlook. Her prize-winning book, 'Double Agent Celery' recounts the incredible story of her spy grandfather, Walter Dicketts, who was sent into Nazi Germany by MI5 during WW2, to infiltrate the German Secret Service in the guise of a traitor and bring back crucial secrets. Interrogated, drugged, and plied with alcohol, Dicketts survived to tell the tale. It took Carolinda seven years to research and write this book and, in the process, united a family and rewrote history. Sadly, Carolinda's mother died without ever knowing his name.
