Actually the cake was quite good, you know he can bake really well if he wants to. (Actually, you know who really bakes well? Mr Snape. It's not something I think he'd like Sirius to know, though, if he doesn't already.) Anyway, it had pink icing and little balloons on, which if you touched them popped into little strips of confetti.

I can't quite imagine Bellatrix drunk on firewhiskey, though. You'll have to recreate it for me.

I'm reasonably certain Hydra was stuck training with Auror Crouch.
