"Is there anything you'd like from Grimmauld Place? I don't stay there very much unless I'm working on something secure," she said after a moment. "I don't know if there's any of Sirius' possessions there, but if you'd like to come take a look, please do. I'm sure there are things I've missed."
She felt like she should say something more, something intelligent, but words simply wouldn't do right now.
