Frank and Joe Hardy finish up a case helping a fellow ATAC (American Teens
Against Crime) agent, whose sharp-eyed fans may recognize despite her Alias.
Things seem to quiet down when ATAC sends Frank and Joe undercover to
investigate a new Mall opening in Bayport, due to several suspicious
accidents there. But things get exciting when the night before the big
opening, Joe, Frank, and seven others are mysteriously locked in the mall
-with a murderer on the loose. If that wasn’t enough, everything that could
go horribly wrong in a mall, does. A flood caused by water beds. An
electrocution at an electronics shop. A bow and arrow used to kill in the
Sporting Goods store. A runaway elevator. A damsel in distress in the dress
shop. Fire in the food court. And much, much more.  Ages 8 to 12.
