"That's enough of this foolishness," Richard replied curtly, sliding the paper back across the table without even bothering to look at it. "I've told you what to find and where to find it, offered Ms. Weasley full access to my flat, offered to submit to the Imperius and Veritaserum without resisting if you bring in another investigator, and you still play little paperwork games. You know as well as I that three drops of Veritaserum would have me answering everything you ask, just as honestly as I've done before, but you'd have your proof, since my word doesn't seem good enough for you."
He slapped one hand down on the table in emphasis, "Unless you think I've somehow smuggled the Vertaserum antidote and Polyjuice in with me, and have been taking them all along here, you know good and well that would quickly resolve any questions you have. You're just enjoying playing your little power games. You can be assured I'll file a complaint about you with your supervisor, and with the Minister too, if I have to."
