Martin Noble – Bloodbath At The House Of Death (Star, 1984)
There is a curse on Headstone Manor – and a team of top scientists have arrived to investigate the phenomenon. But they will shortly be engulfed in a deluge of terror. For tonight is the Night of Blood – ringed in rhesus negative on the calendar of fear. The night when the Sinister Man will lead the locals in a ceremony to herald the return of THE MASTER. Can you take the Bloodbath? Or will you too die laughing?
