Ooh, I did enjoy this creepy little tale. Lots of chills, and you're never quite sure whether Stephen is really being haunted or if he's just suffering from altitude sickness.
And I loved the descriptions of the clothing and food. Paver has obviously done her research into the climbing expeditions of the 1930s, and they're a far cry from today. No breathable fabrics or energy drinks in those times. Woolly jumpers, mugs of hot tea, and peach brandy seemed to be what kept these climbers going.
