'Why do you think I set additional privacy spells on the room?' he asked with a smirk. 'We Slytherins learn the most useful spells...like the ones that ensure your privacy by keeping everyone else away,' he added as he kissed Percy again.

The Lestranges were more or less impossible outside of battles and attacks, they knew that, but perhaps if they could figure out who'd created the virus - and if he wasn't permanently living in Upper Slaughter - there would be a chance to catch him. Or her for that matter.
