Riva helped him up. "Papa, it's control yourself you must. The last time—remember?"
But he only shook her off and went bounding through an archway. His hectic progress through the house was punctuated by sounds of crashing destruction.
"Honestly," Riva said, spreading her hands, "what to do with him I don't know."
Cassidy continued staring in the direction the old man had gone. "He's wrecking the place!"
"That he is," she admitted sighing. "And such a nice joint it be, too."
"He's just plain nuts!" said Mason.
Riva smiled. "But it's so much fun he has."
Cassidy moved away to get a better view of a silvery gray screen set in the wall and flanked by twin rows of dials and knobs.
"You got stereovision, Riva?" he asked.
Mason went over and twisted several of the controls until a soft light began suffusing the screen.
