Despite the quaint lace curtains and flaking blue paint, the little wooden house in Stolbova is not your average Siberian cottage.
It is encircled by motion detectors and 360-degree security cameras. A web of high-power cables slinks on to the grounds from the street. Round the back, hidden behind tall metal fences, two low, barrack-like additions stretch out over land that, in the past, might have been a cabbage patch.
