I would like to offer my grateful thanks to those who gave so generously of their time and expertise during my researches for A Winter Grave. In particular, I would like to express my gratitude to Dr Steve Campman, medical examiner, San Diego, California, USA, for his advice on forensics and pathology; Mo Thomson, photographer, whose amazing still and drone photography substituted for my eyes and ears in Kinlochleven and on Binnein Mòr, when Covid-19 made it difficult for me to travel. Mo’s virtual eVTOL flights from Glasgow to Mull and through Glencoe to Loch Leven, as well as his simulated flights to the summit of Binnein Mòr and into the corries, provided stunning insights into the landscape; Professor Jim Skea, co-chair of Working Group III of the United Nations Intergovernmental Panel on Climate Change (IPCC), and member of the UK government Committee on Climate Change for his advice on my climate change scenario; Cameron McNeish, author, Scottish wilderness hiker, backpacker and mountaineer for his insights on snow, and climbing Binnein Mòr.
