Another one is the Jabberwock from Lewis Carroll's 'Jabberwocky'. It is a strange and menacing creature that the hero has to slay. 'Twas brillig, and the slithy toves did gyre and gimble in the wabe; All mimsy were the borogoves, and the mome raths outgrabe. And then came the Jabberwock, with its jaws that bite and claws that catch, making it a very brutish - like enemy.
Some other names that would be suitable for mafia stories are 'Mafia Riddles', which implies the mystery and puzzles associated with the mafia. 'The Forbidden Mafia' gives the idea that the mafia is something that is off - limits or not supposed to be known. 'Mafia's Trail' could be used to suggest following the path or actions of the mafia, like a detective might do in a story. These names can add intrigue to your mafia story.
Well, you could also consider names like 'Love Unveiled', which gives a sense of discovery in the love story. 'Eternal Love's Tale' is also great as it implies a love that lasts forever. And 'The Love Quest' can be used when the story is about characters searching for love.
