"I hex my room," said Frances, taking a bite innocuously, "My parents aren't magical, and my brother doesn't have the ability to break it. Aside from that, I still have one of Lexy's old charms for the house." Seeing Matt's quizzical expression, she continued, explaining, "It's a bit of spellwork she came up with to safeguard the Conclave families back then. She got the idea from Sirius, I think, I'm not sure. I don't know the details, but it's worked quite well so far."
She smiled then, and reached into her purse discreetly to pull out a wooden object that looked for all the world like a coaster, which she handily and very discreetly slid underneath her drink. "Plus there's this. It's something Lexy and Benjy came up with--it's a scrambler. Whenever we start talking about something Conclave-related, eavesdroppers will just think we're talking about Quidditch. Of course, it's not as useful in a close range situation, but still. Can't be too careful."
