May only Mag reply that? :-)
Have you solved the first Deadulous club riddle? On cerfax tower? Did you get that hint - that flag symbol? You should then compare it with the list that can be found in the same screen as the tower, on the left edge of the screen. Take the item in your hand and compare it with the correct symbol - and you should get it on the map!
