AMERICA'S TOP TEEN DETECTIVES TEAM UP WHEN A CRIME WAVE HITS THE HIGH SEAS
NANCY DREW is enjoying a luxury cruise aboard the ship where her friend George is the new social director. It seems like great fun until Nancy overhears a plan to sell CIA secrets to another country. Her vacation turns into a high-risk hunt for a deadly secret agent.
THE HARDY BOYS are working undercover on the same cruise ship -- Joe in the kitchen, Frank as photographer -- trying to track down a dangerous group of thieves who prey on rich passengers.
But when murder comes aboard, Nancy, Joe, and Frank find they're in the same boat -- facing death on all sides...in DOUBLE CROSSING.
