Page "The Puppet Masters" Paragraph 11

Called in by " the Old Man ", his boss and the head of the organization, they go to investigate the report of a flying saucer landing in Grinnell, Iowa after other agents sent earlier fail to report back.

With them is another agent named " Mary ", a stunningly beautiful redhead.

Sam is informed that her life is only slightly less precious than the Old Man's, and that he ( Sam ) is the most expendable.
