LOL! Maybe as an alias for 'The Prince', but not HKS.
Oh, duh on me - I was only thinking of the "Max" part for "maximum amount of drugs" - shows where my mind is - didn't even think about the "Peter" part, lol.
Was just also thinking about a funny coincidence - in another crime I sleuthed forever and ever, we had a mysterious lady in L.A. we "chased" (not Michelle) all over trying to find - and her name was Anna Katz.
