Bassie & Adriaan found the package
Bassie en Adriaan: De Geheimzinnige opdracht
Bassie & Adriaan have finally found the package. The package was next to a port barrel from 1870. Bassie is curious about what's in the package, and wants to open the package ''just'', but Adriaan stops Bassie just in time. Then it turns out that there is also a letter with the package. Where should Bassie & Adriaan go next? And to which country?
