"But what happened this time?" "He has disappeared!" Majors blinked. "Just like that?" Dr. Pollard smiled and nodded. "Just like that!" Majors thought for a moment.

In that case it is best to do something quickly to protect the innocent. But in Carroll's case it is an intangible—remember the case, Majors?" "Of course." "Well, it hasn't changed a bit.
