"Sorry, Boss." Tony said as he passed by Gibbs towards the showers. Once in the showers, he asked the question on everyone’s mind. "Who would send us a letter with anthrax?" He called out over the sounds of running water. Anthrax was the most recent concern for biological attacks via powder. There had been a lot of news reports about people getting sent it in the mail. Normally anthrax being a no-maj bio attack would mean Tony wouldn’t need to worry, but someone with enough potion skills had figured out how to make a magical copy that looked exactly like the no-maj version and made it as easily available.
