After 8 hrs' struggle & unusually little help available here I am forced to appeal to you to help at least on the 5 asterisked clues since I have little knowledge of those authors & googling hasn't helped much:
Money to throw away in game :?U?D?????
Form a circle on high ground:??A?I?E CLIFF
12's prince softly?:H???? (12 is "half")
Safe 24 (A):P???? (24 unknown to me)
drink to familiar beast:??D??
Even then I still have several others to solve,but please help here first,or I might as well forget it.Pity,though.
