After months of training and preparation, Andrew and his wife Fay joined a small group of intrepid explorers to try to reach the summit of Mount Kilimanjaro in Tanzania. As the only mountain in the world that you can walk up, the ascent will take at least four days of intense walking.

As conditions on the climb become more and more challenging and they leave the cloud layer below them, so the effects of altitude sickness start to have a significant impact on members of the group. The final ascent to the summit is timed to watch the sunrise but is an intense and gruelling challenge during which Andrew starts to become affected by the lack of oxygen. Whether he can make it to the summit is in question, and even if he does, how will he make it back down?

Andrew was a police officer in Northamptonshire for 30 years, rising from the rank of Police Constable to Detective Chief Inspector and was an accredited Senior Investigating Officer, licensed by the Home Office to investigate the most serious of offences. Later, as the deputy head of the the Professional Standards department (the real life 'Line of Duty'), he was able to use his detecting skills again.

Andrew is a keen cyclist and open water swimmer as well as a qualified Open Water Lifeguard.
