'The Believers' by Barry Oringer

David Vincent has successfully managed to organise a small group of ‘believers’ to his cause; headed by Edgar Scoville, they offer financial help and their business and political connections to aid Vincent in his campaign to alert the world to the presence of the alien invaders. But after a secret planning session, the group is attacked by aliens; several members are killed, and Vincent himself is captured and taken to an underground base for interrogation…
