Problem

This is our roof. Children from behind and to the side come over to play a lot but they also steal. R&E have their tiny bedroom on the roof (not the door in the photo, that's our shed). Someone has been coming in stealing their stuff. A lot has now gone including L's very precious china doll. The girls suspected who it was then saw a bag of theirs in this girls room. When challenged she said she'd seen it in their room and wanted to 'look after it for them'. It's been emptied of stuff. We're not too sure how to proceed. It will probably take J talking to the dad but in a shame culture we can be pretty sure that's the end of what is actually quite a nice friendship :(
