Quickly, before I have time to think it through and get scared, I scurry over to the ladder and clamber up. For the first few moments I feel hideously exposed, but that’s just irrational fear talking. Then I’m ten meters up, right next to the metal housing of the light. I can feel its heat on my bare skin. I feel more exposed than ever, but I know that’s not the case at all. Anybody looking my way will see only the light. I turn around, hanging on with my left hand and settling the H & K in my right.
