So, only if it seemed that you don't know why something of it is not right, post it and I'll explain. Otherwise, I can only advise you to try to find an answer which fits well with all the things in the riddle (as always).
P.S. And for everyone: if any of you thinks he is on track (or thinks he is totally out of track) and wants a hint, please ask for it, because I don't want to spoil it to you by telling too much when you want to come to it by yourselves, and on the other hand, I don't want you to drown in puzzles when you'd appreciate a hint.
