<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">pack of plotters</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 cabal that I've seen before include "Caucus" , "Group of conspirators" , "Small group of (eg political) plotters" , "Secret political group" , "Clique of plotters" .)
