Sara stopped walking suddenly.
Her breath came out in small white clouds and what was visible of her face was flushed with cold and physical exertion.
The wind funnelling through the river channel was strong and biting, whipping the hair that was sticking out of her beanie about her face.
Pushing her hair back, she turned toward Grissom who had stopped beside her. "Is this it?" she asked, pointing to a point over on the left fifty yards or so away.
Grissom certainly hoped so. Lifting his sunglasses, he peered into the distance. The sun had disappeared behind a blanket of grey, snow-laden cloud, dropping the temperatures to well below freezing and reducing visibility. He needed a break, and soon.
