do you mean, Pat?" Ross growled.

She turned to him. "We haven't given Don the chance to prove which one
of us is right. One day is insufficient. Half the things he wished to
do, such as sneaking around picking up stock tips in Wall Street and
inside information on sporting events...."

"Hey, take it easy," Crowley protested. "I was just, like, curious."

Ross said heatedly, "That's not fair. I'll admit, I, too, thought of
exactly the same possibilities. But _thinking_ about them and going
through with them are different things. Haven't you ever thought about
what you'd do if given the chance to be world-wide supreme dictator?
But, truly, if the job was offered, would you take it?"

"Good heavens," Patricia said disgustedly, "remind me to break off our
engagement if I haven't already done it. I hate overpowering men. All
I'm saying is that we'll have to give Don at least a week. One day isn't
enough."

Dr. Braun cocked his head to one side and said uncomfortably, "I'm not
sure but that in a week's time our friend Don might be able.... See
here, Don, do you mind going on down to the hotel's bar while we three
talk this through?"

Crowley obviously took umbrage at that, but there was nothing to be
done. Frowning peevishly, he left.

The doctor looked from one to the other of his associates. "By Caesar,
do you realize the damage friend Don could accomplish in a week's time?"

Patricia laughed at him. "That's what I keep telling the two of you. Do
you realize the damage _any_ person could do with invisibility? Not to
speak of giving it to every Tom, Dick and Harry in the world."

Ross said, "We've started this, lets go through with it. I back Pat's
suggestion, that we give Don sufficient serum to give him twelve hours
of invisibility a day for a full week. However, we will ration it out to
him day by day, so that if things get out of hand we can cut his
supply."

"That's an idea," Patricia said. "And I suspect that within half the
period we'll all be convinced that the process will have to be
suppressed."

Ross leaned forward. "Good. I suggest we three keep this suite and get
Don a room elsewhere, so he won't be inhibited by our continual
presence. Once a day we'll give him enough serum for one shot and he can
take it any time he wishes to." He ran his beefy hand back through his
red crew cut in a gesture of satisfaction. "If he seems to get out of
hand, we'll call it all off."

Dr. Braun cleared his throat u
