Ghost Hunter part II

A Russian submarine is spottet from the ferry, and the maritime surveilance planes take to the sky to try to locate it. It's almost like in the Cold War. But it never happened before, that the whole area is taken over by NATO. The official explanation is, this is a logistics exercize. No one believes it, since the Russian Northern Fleet have left its moorings in Severomorsk on the Kola peninsula to conduct unspesified drills in the northern waters.
The local police chief try to keep an eye on everything, and must help an engineer to get into the no go zone to fix a broken line on a telefon post. It seems like, someone have used the connection to Internet to call home. Fyodor Lawroskin is a biology student at the University of St. Petersburg, and a bird watcher. He disappears while tracking through the mountains to maintain the cameras the bird watchers have deployed in the terrain to watch different species of birds.
An old freak of unknown origin has also disappeared. He used to take odd jobs, and no one knew where he came from, or where he has gone. The whole island is under surveillance, the mobil phones are bugged, and the Internet too. There are observation posts along the shores, and people must stay in the villages and on the roads. There must have been unofficial diplomatic negotiation, because the Northern Fleet return to Severomorsk and NATO's forces pulls out.
But there are Americans left, and one night a lieutenant is killed. It's summer, and the midnight sun is shining. Still no one have seen the lieutenant after he left the pub.
