Simon I've been trying to call you, but it seems like your phone is turned off. I don't know where you are right now. I don't know if Clary's already told you what happened tonight. But I have to go to Magnus's and I'd really like you to be there. I'm scared for my brother. I never ask you for anything, Simon, but I'm asking you now. Please come. Isabelle. Simon let the letter fall from his hand. He was out of the apartment and on his way down the steps before it had even hit the floor.
