"Keep up your masquerade as a bank messenger and try to find out, as if you were an ordinary curiosity-seeker, all you can about Cavalier Institute. You've made a good start with the Garet girl. Get to know her father, the professor."
"Yes, sir." Don realized with embarrassment that his little romantic interlude with Alis must have been eavesdropped on. "Are there any particular times I'm to report?"
"You will be reporting constantly. That's the beauty of this radio."
"You mean I can't turn it off? I won't have any privacy? There'll always be somebody listening?"
"Exactly. But you mustn't be inhibited. Your private life is still your own and no one will criticize. Your unofficial actions will simply be ignored."
"Oh, great!"
"You must rely on our discretion, Sergeant. I'm sure you'll get used to it. Enough of this for now. We mustn't excite Clark's suspicions. Go back to him now and carry on. You'll receive further instructions as they are necessary. And remember—don't be inhibited."
"No, sir," Don said ruefully. He went back to the printshop, feeling like a goldfish bowl.
