Plot to Kill Caesar (ABSENT)

If I was Cassius, or Brutus, and needed to make a plan to kill Caesar, I'd probably plan to do it in his sleep. I would find out when he would be at home. Then I would obtain some kind of poison or something that would kill him. I would then get someone who knows a lot about him and is his friend to put the poison into a drink of his (with the persuasion of some money). After the deed is done, I would kill the person who had given him the poison so that no one except I knew of what had happened. So in this way, no one would suspect me and everyone would think that he died due to some weird sickness or other cause.
