The Mysterious Schoolmaster

In the small coastal Swedish naval town of Nordvick, two teenagers—Michael and Cecilia—are thrown together by circumstance when they begin to notice highly suspicious behavior from their new physics teacher, Mr. Engman. When they witness him entering the school building at night and meeting mysteriously with shady mechanics, they suspect military espionage is at play. Their curiosity soon draws them into a dangerous game of detective work that puts them in real peril. [1, 3, 4]
