<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">hercule's creator</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for agatha that I've seen before include "...... Christie, author" , "- - Christie (lit.)" , "-- Christie, English novelist" , "- Christie, twentieth century crime novelist" , "...... Christie wrote great detective stories" .)
