Homing spider!

Anyone who reads this regularly will know that not too long ago I mentioned that this year I have been overrun with spiders.
I haven't seen too many just lately but over the last four nights I have had a rather large one in the front room. We go through the same routine at roughly the same time every evening and I swear he/she must wear a watch!
About 8pm the spider, which is about an inch and a half across, marches in through the door and follows the same route across the carpet and under the chair opposite where I sit. Then it goes along in front of the fire and disappears under the cabinet that the television is on. I am certain I can hear it's footsteps as it marches around.
Anyway, while it is under the television cabinet, I go out into the kitchen and fetch a glass and a piece of stiff paper then wait for it to reappear. It always takes the same route back about ten minutes later so I catch it in front of the fire and take it outside.
The first two nights I released it outside the back door but somehow, it found it's way back and appeared at the same time the second and third night. On the third night I released it out the front door but again it was back at the same time last night.
In order to see how clever this creature is, last night I kept it in the glass and then put it in a jam jar. This morning I had to go to the garden centre which is about half a mile away but I took the long route and released it in the shrubs on the car park.
I will be very surprised if it marches in tonight! Perhaps I should have marked it with some paint.
