The first case for Leander Lost, the new detective star in the crime scene. The September light in the Algarve is of enchanting beauty. At Faro Airport, Sub-Inspector Rosado and her colleague Esteves welcome a lanky guy in a black suit and narrow leather tie: Leander Lost, a criminal commissioner from Hamburg, serving for a year with the Polícia Judiciária. A unique team-building experience begins as the Portuguese sub-inspectors realize that their new colleague from Germany is not only oddly dressed but also behaves strangely. They slowly start to uncover the murderer of a private detective, as well as the fact that Leander Lost's peculiarities are due to Asperger's syndrome—and that his island talents are extremely helpful in solving the case involving dirty dealings.
