What the story is about:
Zanza was a very special mosquito.
Her ideas were unlike those of her friends and besides that she was fond of diamonds.
In a dream an old mosquito had told her how to obtain some of those beautiful stones, huge ones of 40 carats!
She took care of companions in need, definitely did not drink blood anymore and never did anything indecent.
But was she really a good mosquito or did she live the life she lived simply because of greed?
