Mr. and Mrs. Andrews
Bob's parents have cameos
in many of the stories and give us a glimpse of his home
life. Bob's father is named Bill (revealed in "Green
Ghost") and works as a reporter for the Los Angeles
Times. In addition to serving as a source of wisdom for
the pivotal clue in several stories ("Stuttering
Parrot," "Fiery Eye"), Mr. Andrews has
taken a more active role in some stories ("Green
Ghost," "Shark Reef").
Mrs. Andrews is one of the first characters to whom we're
introduced in "Terror Castle." She's a frequent
message-taker for Bob but has to write down the messages
from Jupiter because they're not ordinary messages. Bob
tries to give his mother a tutorial in what Jupe's
messages mean in "Stuttering Parrot" ("the
bird's on the wing, the case is the thing") but even
after that she still has to write down the messages.
An interesting side note is that the first chronicled
mystery solved by Jupiter Jones occurs prior to the
actual formation of the Three Investigators. It is the
case of Mrs. Andrews' missing engagement ring, described
in the early pages of "Terror Castle."
