The great niece and biographer of one of Britain's most famous mountaineers is continuing a tour where she talks about the possibility that he may have been one of the first men to climb Everest.
Julie Summers will discuss the life and times of her ancestor Sandy Irvine, who along with George Mallory perished in a bid to climb the world's highest mountain in 1924, something that may inspire some to get their climbing ropes and try some mountain challenges of their own.
While Edmund Hilary and Tensing Norgay are officially credited with being first to the top, Ms Summers will explore the unanswered question of whether Mallory and Irvine reached the summit 29 years earlier.
The issue remains shrouded in mystery, with the discovery of Mallory's body in 1999 doing nothing to solve the riddle.
This week's talks will be held in Buxton Opera House tomorrow (October 5th) Venue Cymru in Llandudno on the 6th and Theatr Brycheiniog in Brecon on October 7th.
British conquerors of Everest include the only man from the UK to climb all 14 of the mountains over 8,000 metres in height, Alan Hinkes.
