Joe and Frank Hardy investigate the disappearance of children from an amusement park ride.

"When a sinkhole opens up and swallows one of Bayport's historic statues, Frank and Joe suspect something--or someone--shady at play. They jump at the chance to investigate ; Joe as a member of an urban exploration club, and Frank as photographer for the school paper. But in the thick of their search, the boys stumble upon an entire underground city that's been abandoned for years. Now the city is home to a cultish band of criminals who plan to take over Bayport. Frank and Joe are determined to shut down the crooks, but after being barreled down by a boulder and nearly squashed by a runaway train, they have to wonder: are they in over their heads?"--Dust jacket.

"To die or not to die? Frank and Joe Hardy ask themselves that question and their answer may shock you! They decide in the best interests of their client, everyone would be better off if the Hardy Boys were dead! But before they launch their journey into that long "Hardy day's night,' the Undercover Brothers face their 'Opposite numbers,' the deadly Noir sisters, seek out killers at the 'Board to Death' extreme skate boarding competition and at the All-State Drama competition, where one of the Hardy Boys falls deeply in love--with the wrong girl!"--Back cover.

On the first day of their trip to Paris the Hardy Boys are woken up early in the morning by fireworks that are part of an elaborate cover for the heist of a priceless artifact. Frank and Joe are determined to find the culprit.
