AT FIRST YOU DON'T NOTICE THE FACE ON THE WALL, BUT THEN IT SPEAKS TO YOU.

"HELLO," IT SAYS.

YOU ARE UNDERSTANDABLY SURPRISED BUT FIND ENOUGH SENSE TO REPLY TO ITS GREETING. "HELLO," YOU SAY, "IF YOU DON'T MIND MY ASKING, WHO ARE YOU?"

"I AM THE GREEN MAN," IT ANSWERS, "AND I KNOW THE WAY OUT OF THIS MAZE. I MIGHT TELL YOU HOW TO GET TO THE END IF YOU AGREE TO PLAY A LITTLE GAME WITH ME."

"WHAT KIND OF GAME?" YOU ASK.

"SIMPLY ANSWER THREE QUESTIONS CORRECTLY AND YOU WILL MAGICALLY BE TRANSPORTED OUT OF THE MAZE," THE GREEN MAN SAID.

"AND IF I DON'T ANSWER THEM CORRECTLY?" YOU ASK.

"IF YOU GIVE A WRONG ANSWER TO ANY OF THE QUESTIONS, I WILL SEND YOU SOMEWHERE ELSE, BUT WHERE I SEND YOU WILL DEPEND ON THE ANSWER YOU GIVE."
