Wenn der Zirkus kommt

From the back of the book (translated):

Sometime - mostly, when old age comes - even the richest merchant notices that ducats alone make not happy, and he asks himself which errors he has made in past. Where he could have given his life a turn, and if it was clever to always follow the gold and not the love. to always follow. Such a business magnate assigns the heroes to find a love from days long gone. The search soon leads to a small traveling circus, to a troop of friendly, merry jugglers, with which the heroes quickly become friends. However all too soon they notice that the shade of a dark past rests over the colorful crowd, and they must experience with their own body that old maledictions and curses are often the most terrible.
