You're riding on the school bus one
snowy morning. A police car stops the
bus, and Detective Minkly climbs
aboard. "We have reason to think that
there's an alien on the bus," he says.
"There's been a UFO report, and we
found tracks in the snow leading from
the UFO to one of the bus stops."

"I believe that!" exclaims the bus
driver. "There are usually only three
kids on the bus by this time, but today
there are four!" He moves the rear-view
mirror so he can see the kids on the
bus.

Your friend Mary leans over and
whispers to you, "How does he know
that? He doesn't look like our usual
bus driver."

Detective Minkly knows you from the
previous capers you've cracked
together. But he doesn't know Mary.
He looks at her and says "Who are you?"
She says, "I'm Mary Murphy." While
Mary and Detective Minkly are talking,
you notice that Mary's freckles are
gone. Mary has ALWAYS had freckles.

"And who are you?" Detective Minkly
asks a boy with blond hair. He says,
"My name is Freddie Ferguson, and I've
just moved here from Florida. This is
my first day in school." "Oh," replies
Detective Minkly. "Welcome to our
town.

"How do you like the weather we're
having?" Detective Minkly continues.
Freddie shrugs and says, "Fine, I
guess. It's not much different from the
weather where I come from."

Detective Minkly turns to another
unfamiliar face, "And who are you?" The
girl squeaks, "I'm Yolanda Young. You
don't know me--I just transferred from
another school."

"Sorry, I guess I was wrong about the
alien," sighs Detective Minkly, as he
turns to leave the bus. "Everything
seems to be in order here." But you've
noticed something Detective Minkly has
not. Can you and your 221B Mystery-
Solving Computer solve this puzzler?
