Noooooo. There's no need to send Idris. I've taken your advice to heart and I'm sure we can sort it out ourselves. Dad probably didn't do it. I mean, it's murder. Pretty sure that would be setting a bad example for all the other Aurors! And if he did he'll probably get away with it.
Did I mention there's no need to bother Idris? He's probably busy with...wedding planning. No need, truly.
