Dear Mark Millar:

Green tea has caffeine, you putz. Not as much as an Americano, sure, but hardly OK for someone who has "given up caffeine for Lent."

Than again, since this is a Mark Millar book, it's not unlikely that Washington D.C. police chief Blake Morrow is an incredible jerk who is purposely trying to get one of his "inner circle" to break her Lent pledge.

I mean, it couldn't because you were just too lazy to actually look something as basic as that up, right?
