Over Christmas my sister took some bags to my grandparents and I took the others we then realised she had my 400ish pound shoes in a bag of mine. I said she could have some picture frames hadn’t used she wanted to pick them up so I told my partner she would be dropping them off and picking up the frames. Partner was at home all day and I was at work he then text to say he’s off out and spoken to my sister he’s left the frames outside and she will drop the shoes off. I text her saying keep the shoes in the car I’ll come get them I don’t want them being left outside all day said the same to partner but they both said it would be fine there suede and it was raining all day yesterday. When I called my sister last night to come collect them she said there outside my house I’ve gone home and there not there. No ones seen them they’ve clearly been stolen from outside my flat door no cctv either
