Hi there
Read most of this fic ages ago and then lost track of it. Basics were:
Set in the early 20th C, 1940s maybe??
Buffy's a nightclub singer who works for mafia dude's son Angel, who she's also dating. Angel's dirty as they come and someone has hired Spike to kill him. He and his team, consisting of Willow and someone else (Gunn maybe? ...or Giles?? ...think it was probably Giles) reluctantly take the job, as it's big money and Spike's last kill before going straight.
When Spike's team hit town, Buffy and Spike meet in a bar, and she ends up going back to his hotel before disappearing in the morning without telling him who she is. Later, when Spike goes to Angel's club to check it out, he sees Buffy again and obviously things get more complicated (there's this great scene where he sneaks to see her backstage and they get all naughty on her dressing table while she watches them in the mirror).
Spike decides to send Williow in to the club undercover. Wesley runs the club for Angel (though he seems fairly straight), and he and Willow meet when she starts working in the club as a coatcheck girl and promply fall for each other... and that's as far as I got *sob*
Sounds good, doesn't it

If anyone knows where I can find this fic please please please let me know.
All the very best to you lovelies
