Hi all. I am having trouble dropping the letter on Gaius Maro after killing him. I bring up my books, highlight the letter and when I hit the button on my PS3 to drop the letter, I get a message that I cannot drop letters involved in a quest. Has anyone had this happen to them and if so, how do you fix it so you could finish the quest? Thanks for any and all help. Danny Dunk8009

Are you actually trying to drop it, like, on the floor? You need to search him and put it in his inventory - you're supposed to be planting it on him, not leaving it nearby!

This. Go into the part where you can loot his body, and take stuff from his inventory, then go to your inventory and plant the letter.

This goes for reverse pick pocketing as well.
