This laugh you can hear in the slaughterhouse ...
Eric Vauclare swoops down into the town of Harefield and ends up attending a meeting of the Supreme Godhead Outreach Church.
He decides he can infiltrate this pseudo-Christian cult and use it to build up his community of bloodsucking 'immortals'. In not too long a time, he thinks, the whole of England, then the world, will be undead.
Things go well, church membership is growing and on summer nights his vampires are feeding out in a cornfield in nearby Crouch Corner.
At the same time however, a stocky undercover cop by the name of 'Suggie' Southgate is dogging Vauclare's trail.
