I've wondered if the landlord did see the house, and that's why the eviction notice she didn't mention until tonight. I feel a little dirty for speculating in this way, but if I were a landlord, and I saw what I saw tonight...

I get the impression that she's outlived her relatives, and that now she relies on few neighbors, her lawyer, and a few old friends/acquaintances to lend a hand every now and then.

You're not the only one to suggest calling an agency for advice, and I think it's an excellent idea. I'll do that in the morning, and hope that they can steer me in a direction that'll help her but limit my own involvement, because yes, I'm very much afraid of this consuming my life. :/ *hugs*
