They'd always trusted him until now-.A morning flight over Helsingor turns dangerous when the pilot, Matthias Karlsson, blacks out without warning. Almost as terrifying is the find thirteen-year-old Peter Andersen makes in the cockpit a hidden handgun! When Matthias comes to just in time to save their plane from crashing into the sea, Peter puts the shocking discovery behind him for the moment.
Certain Matthias is hiding something, Peter persuades Henrik Melcoir to join him in spying on the man, and the friends witness a suspicious nighttime meeting with a foreign ship captain. What's worse, a mysterious stranger appears to be spying on Matthias, too.
Suddenly, Peter, Elise, and Henrik find themselves at the center of a dangerous plot. If Matthias is involved, are the Melchoirs in danger also? If so, Peter may be about to lose his best friend!
