Some of you may remember a thread I had a while back about nanny cams. Well, the situation has progressed and I need the peculiar combination of intelligence and deviousness that security folks tend to have...
For reasons too long to go into, she is no longer allowed in the home without me. My concern is that two days of the week I work and she does not. She leaves with me in the morning, and doesn't have a key, but we rent an apartment. I know they'll let her in if she asks, and they once even let us borrow their master key for a full day to make copies, so she could theoretically have gotten a copy made.
So what I need is this - some way to 'rig' the front door so that I know if she's been inside without me. The best I can come up with is a piece of clear scotch tape at the top corner, but if anyone has a better suggestion I'd love to hear it.
