The only way to get into my last house without being seen was through the un-curtained conservatory.
If I was away, apart from timed lights and radio, I would make a large, sleeping body on the sofa......pillows, a wig and a duvet.
On the floor I'd leave a plate with supper remains, a can of beer and a large studded dog collar.....☺
Don't know if this deterred anyone....but I wasn't ever burgled and Grandma's lodger amused the kids.....x
