Looking for a book about werewolves and The Spear of Longinus?

[mojojojo]

Several years ago I bought a paperback novel from a used bookstore.
Unfortunately I lost it soon after. It was set in the WW2 era and it had
something to do with an an evil Asian monk who had green hands (at one point a character to them as "Little Green Monkeypaws") that was using
the Spear of Spear of Longinus for nefarious purposes. An American detective
(who was also a werewolf) was trying to stop him.

Does any one have any idea what this book was?
or if not can you recommend any site that help find the names of book (is there
something like imdb.com but for books?)

I suspect the OP is looking for Richard Jaccoma’s books. The first is Yellow Peril: Adventures of Sir John Weymouth-Smythe (78). It involves a villain who is a Fu Machu pastiche, Nazis, the spear of destiny/Longinus, and a werewolf. There are two semi-sequels more focused on the werewolf detective called The Werewolf’s Tale (88) and The Werewolf’s Revenge (91).
