The engineers resumed their work. The roar of the diesel generator echoed through the valley, and the sparks from welding were especially glaring under the gloomy sky.
Chesteron climbed onto a large boulder by the riverbank and observed with binoculars. Fog was beginning to gather in the valley, decreasing visibility. He glanced at his watch: Two in the afternoon. In the winter Highlands, it would be dark by four.
The radio crackled, and it was the Sergeant Major from Team B: "Traces found on the north slope, someone has been active recently, at least ten people. Found some cigarette butts, and this—"
The channel was filled with static, followed by the Sergeant Major's voice, kept very low: "...tripwire, connected to an 82mm mortar shell. It's been disarmed, but there might be more nearby."
"Keep searching, be careful."
