<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">author sinclair</span>' is the definition.<br/ ><span class="explanation-format__explanation">(American writer Upton Sinclair)</span><br/ ><br/ >This is all the clue.<br/ ></span>

(Another definition for upton that I've seen is " West Ham's Park".)
