Thank you so much for your flattering words. I'm really pleased that you thought that I'd captured the relationship between Peter and the other Marauders. I tried to piece together a picture of that from the canon evidence -- Rosemerta's observations and the pensieve. I can't help but feel a bit sorry for Peter, although the betrayal is of course unforgiveable.
I'm very happy that you liked their awkward, emotionally under-expressed English men's courtship. Thanks so much, again, for your lovely words.
