My friend Barbara and I traveled to Split, Croatia, where Book 3 in my Blood & Wool 16th-century mystery trilogy takes place. While there, I learned that Daniel Rodriga was such an important real-life negotiator between Venice and Istanbul that now he’ll be a major secondary character in my mystery. And who knew that Diocletian was among the top ten of all 80+ Roman emperors? His palace, where we’re standing, is the second-largest of all Roman Empire palaces, yet took only ten years to build.
