Alias used by the female Section
agent who accompanied Andrew
Nivens to investigate the flying saucer landing. Afterwards, she
apparently adopted the name permanently, using it when she married Sam
Cavanaugh. She was born into the Whitmanites
(her original name was Allucquere) and emigrated to Venus with
her family, where the entire community had been taken over by puppet
masters and mostly kept in suspended animation until needed as hosts; Mary
spent ten years suspended. The puppet masters, and all human hosts except
Mary, died in an epidemic of nine-day
fever. Mary was found by Venus
colonials and adopted into a mining colony. Her recollection of these events
provided a means to destroy the infestation of puppet masters on Earth.
Sam Cavanaugh (a.k.a. Elihu Nivens)
Alias for an agent of a top-secret U.S. government agency called the Section.
He was assigned to investigate reports of a flying saucer landing in Grinnell,
Iowa. With Mary
Cavanaugh and Andrew
Nivens (his boss and his father), he discovered that the saucer was
real,and that it had brought intelligent parasites to Earth to take over the
population. Although briefly taken over by a puppet
master himself, he played a major role in defeating the invasion. He
seldom used his real name, Elihu Nivens, during the mission, preferring the
alias that he adopted when he first visited the saucer landing site.
