I'll just spoil it for you... Click on the second "rule" on that page.
FWIW, Firefox won't let me select the second rule, while Safari does (having the second rule outlined when clicked on makes the clue more obvious).
Given that one of the other heists (the first one, yes?) was also messed up in Firefox, I'm switching back to Safari for heists this year.
