Any of a number of Swords cards (I though of the 7 first, as celticnoodle did. That's because the Seven of Swords can
bring the connotation of lying-cheating-stealing or other nefarious energies along with planning something out.) I could also see the Ten of Swords (hey, there are a bunch of swords sticking out of a guy who is lying on the ground...how much more explicit can that be!
) Or how about the Three of Swords? The Eight, Nine?
The Tower comes to mind (though if that came up with the Devil, I would first think of a drug overdose.)
I did a reading for a guy one time who had admitted committing a serious crime (though he didn't say what it was), and his question was whether or not he was going to get away with it or get arrested and go to prison. I remember Judgment and Justice came up, and I told him justice was going to be served. (I never heard from him again, so, he may be in prison right now.)
