Surprising confessions come to light as Brooklyn and Malibu team up to protect precious cargo aboard a speeding train headed back to England.

The teen detectives split up into three different groups: one to find Pepper, one to track down Dietrich, and one to keep an eye on Giovanni.

Denholm seems awfully suspicious... until Lady Carson reveals she might have a motive. Ken and Marcus arrive in London. Cassidy makes an unexpected move.

As the gang races against time to stop the culprit, a shocking revelation turns the entire investigation upside-down.

Everyone's a suspect, so the Barbies hunt for clues to clear their names. Are Lady Puddington's muddy shoes a sign of guilt — or just a fashion crime?

Who swiped Martin the Magnificent's crystal? The Barbies consider their suspects while investigating why Madame Celeste is acting even odder than usual.

Brooklyn and Malibu follow Cassidy to Venice, where they're pulled into a fashion-forward side quest and reunite with an old friend.

With the competition looming and Pepper still on the loose, the Carsons need another horse — and someone to ride her. The gang sets a trap for Giovanni.

The Barbies have a plan to rescue the horses, recover the saddle and win the championship, too. But it'll take everyone on the team to pull it off!

The plot thickens as the Barbies suspect summertime sabotage. Meanwhile, Ken finds a clue, Councilman Wynin comes clean and Warlock has a rough night.
