Like this? (4-11) [rab] well, yes, I was aware that was a flaw; I was hoping to get away with a loose sense of ultimate = end. And I want yours to be DEFINITION, but I can't figure out why.
My clue is wrong. Sorry, it should read: This clue might be: "500. Follows solid containing volume of mute's heart" (10) which might give a clue in its own right.
CdM's is either self-explanatory or self-descriptive; rab's is maybe convoluted: vol & ut in cone; 500 = D. PS. Do we really need hidden text in this game?
