This excentric journey into the East, Falco and Helena travel through the Middle East from Petra, all around the Decapolis to Damascus ending in a grand spectacle in Palmyra. Helena is less present and the mystery is a bit longish. This is a reread for me still I didn't remember most of the plot. Still, it's entertaining, well plotted and is almost an ancient world travelogue and a good one. Still 4 stars.
