<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">payable now</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for due that I've seen before include "Payable; deserved" , "Owed, or payable immediately" , "Appropriate - fee - now owing" , "Escort" , "Expected, scheduled" .)
