GUSTAV. No, you are to stay here. You have to be impolite. If
her conscience is clear, you'll catch it until your ears tingle.
If she is guilty, she'll come up and pet you.

ADOLPH. Are you so sure of that?

GUSTAV. Not quite, because a rabbit will sometimes turn and run in
loops, but I'll follow. My room is nest to this. [He points to the
door on the right] There I shall take up my position and watch you
while you are playing the game in here. But when you are done,
we'll change parts: I'll enter the cage and do tricks with the
snake while you stick to the key-hole. Then we meet in the park to
compare notes. But keep your back stiff. And if you feel yourself
weakening, knock twice on the floor with a chair.

ADOLPH. All right!--But don't go away. I must be sure that you are
in the next room.

GUSTAV. You can be quite sure of that. But don't get scared
afterward, when you watch me dissecting a human soul and laying
out its various parts on the table. They say it is rather hard on
a beginner, but once you have seen it done, you never want to miss
it.--And be sure to remember one thing: not a word about having
met me, or having made any new acquaintance whatever while she was
away. Not one word! And I'll discover her weak point by myself.
Hush, she has arrived--she is in her room now. She's humming to
herself. That means she is in a rage!--Now, straight in the back,
please! And sit down on that chair over there, so that she has to
sit here--then I can watch both of you at the same time.
