The team are back together and have some very special guests with them. Some of Philby’s British family have travelled to Saudi Arabia for the start of the next leg of the expedition. This is the first time the two families have met. After a great send off, with eagles soaring above them,  Mark and Reem set out on foot from Old Diriyah UNESCO World Heritage site, a place Philby wrote about. They walk along the Wadi Hanifa and are quickly away from the hustle and bustle of modern Riyadh. Back with their walking poles, their thoughts and of course Philby’s manuscript.
