I had to get away. But, we were surrounded in that little house, just me and Iris. And I never liked Iris: too whiny. So, killing her was no big deal.
The hard part was dragging her body upstairs and getting it through the window. I had to break it, it was one of those that doesn’t open. The noise just attracted more of them to that side of the house, so that was helpful. The horde surrounded the body and began to feast, and I just went downstairs and walked out the front door and down the street unmolested.
