Just got back from the green lanes with the dogs. My Cocker bitch that will only route out game and never play, unearthed a hibernating vole and brought it to me for praise.
Anyway as it was showing signs of coming too in the warm sunlight, I thought it best to leave it to nature to decide if it went back into hibernation or not. I hadn't gone a hundred yards before a falcon of some sort swept down from a nearby copse, but over 300 yards away, and carried it away in one swift swoop... amazing.
Your spider was what's called a house spider. They commonly live in houses, but the myth that they'll always return to the house if you put them outside is just that - a myth. When these spiders evolved there were no houses. They lived in crevices in fallen trees and in caves, and they still do - you'll often find them if you have a log pile in the garden.
