stolen
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">taken unlawfully</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for stolen that I've seen before include "Filched" , "Purloined or embezzled" , "Misappropriated; hot" , "Taken without permission or payment" , "Pilfered" .)
