Monica Helsh,
My belated congratulations on becoming an Agent. If you do not remember me, I was one of the people to assist you in your recent Machine expedition, and while you likely have many problems to deal with, I need to speak to you about something that could potentially destroy Sanctuary if left unchecked.
I'll make myself available at your convienience so we can discuss this; this is best left away from letters for reasons that will become apparent.
