Just about everything here from legends of the Holy Grail to unholy green slime gurgles and gurgles that ingest a sizable number of citizens from the Diocese of Lanchester, England. Before this, however, there is a boiling dither about unsealing the tomb of an 18th century poet and visionary of unsavory reputation. How unsavory the dead man's secret was is revealed after several murders and it takes a sacrificial Nazi war criminal to save the world. Between Gothic mystery and SF lab chiller--it works tombultously.
