Just found this one yesterday; The Mallorca Files.
Two seasons, shown back in 2019. For some reason I never watched them but so glad I discovered them because they are (a) light detective series and (b) are filmed in the magical and totally gorgeous Mallorca. Oh God, how I am longing to return there one day!
Anyway, its not too heavy and really quite entertaining so, dip in and see what you think (and bask in the warm sunshine and beautiful scenery).
