<span class="explanation-format__ClueExplanation">I believe this is a double definition.<br/ ><br/ >'<span class="explanation-format__original">fraud</span>' is the first definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >'<span class="explanation-format__original">trick</span>' is the second definition.<br/ ><span class="explanation-format__explanation">(I have seen 'Dishonest trick ' mean 'deceit' so perhaps 'trick' could also mean 'deceit')</span><br/ ><br/ ></span>
(Other definitions for deceit that I've seen before include "Hypocrisy" , "Fraud, cheating" , "Pretence, cheating" , "Cunning trickery" , "Lying" .)
