It's about 4k- I didn't go that much in the last 'upper floors' to leave it to the readers imagination, but the ending of what happens to Kirk is...well...pretty self explanatory.
Kirk drove his run-down pickup truck along the dirt road. The thing was so broken down that it lacked air conditioning, and considering how it was a hot summer day, that was definitely not good. Both windows were rolled down, but it didn't seem to help her very much.
