Harry took down the spelling, relieved it wasn't as generic as he'd thought. Still it seemed a bit unusual to actually name someone that and he wondered whether that actually was her name. That however wasn't important at the moment.
That bit of news was also very interesting, Harry thought, making note. "Lisa? What's her surname?" If she'd spoken with Thorntwaite so close in time to the incident, maybe she'd have more to say about it. "Thorntwaite didn't have a habit of leaving his wand about, did he?" He doubted it, but best to ask for confirmation.
