YASID: two werewolf novels (different authors)

Finally picked up "Kitty and the Midnight Hour" based on all the
references seen here - very good.

Now I'm reminded of two different werewolf novels that I read in the
early 1990s and wouldn't mind finding again, but can't recall titles
or authors:

First one told the story of a Russian boy of noble family, parents
executed by Reds after the Revolution, he runs off into the forest and
is bitten by a werewolf and joins the werewolf tribe. Later becomes an
Allied agent operating against the Nazis in WW2. I remember more
details if needed, but don't want to spoil anything for others who
might want to read it.

Second one was set in New York in 1930s, main character is hard-boiled
detective, weird supernatural stuff starts happening and he gets
bitten by werewolf and becomes one himself. Fights against
Nazi/Fascist group trying to get sup****t in USA - in fact, he is very
socialist and everyone in the book who is not seems to be some variety
of fascist - no moderates to be seen, and The Rich Are Evile. Nazis
have a variety of undead and weres on their side.

Anybody recognize these?
