M(ary) V. Carey
For many readers of the Three
Investigators, it was a mystery why one of the authors of
the series used initials instead of a first name on the
byline. Of course, with a series that was usually
inclined to appeal more to boys (although many girls also
followed the series), apparently Random House felt that
they shouldn't publicize the fact that a woman was
writing some of the books.
M. V. Carey's first story was "Flaming Footprints"
and like William Arden, her initial books had a lot of
the same elements as that of Robert Arthur. Two of the
major differences in Carey's books became evident as the
series went on. Whereas Headquarters was a centerpiece in
most of Robert Arthur's stories, it did not seem to take
as prominent a role in Carey's stories. Secondly, Carey
seemed to have a fascination for the paranormal, which
she wove into at least four stories: "Singing
Serpent," "Invisible Dog," "Haunted
Mirror," and "Magic Circle."
M. V. Carey with William Arden is responsible for keeping
the series going and deserves credit for writing many
memorable mysteries for the boys.
