The object of the game is to prevent project "Overlord", a satellite which can control people, from going into operation. The men behind this are the chiefs of Gideon Enterprises and the Law and Order party. To stop the satellite, you need to collect the eight pass cards which were issued to the eight scientists involved with the project (one of them being Carl Linsky). Be quick though, Carl's wasn't the first death and certainly won't be the last. So ensure you visit the potential victims before anything happens to them.

Getting out and meeting people is the only way to gain information and to progress through the game. And it's usually a good idea to treat them with respect. Don't go in fists flailing. Be reasonable. It's more productive and you won't get hurt. When interrogating somebody, try to find connections between them and other characters. A great many people in the game are linked and these links will need to be exploited to help you get further in the mystery.
