Need some advice

I'm having a problem with characters and a setting that are almost mutually exclusive. It's a romantic suspense semi-historical (circa 1950). Of course anachronistic values essential for motivating character actions is the issue. If you have experience resolving problems of this sort and would like to see a summary of the project and offer advice, please e-mail me. KDKwriter(at)gmail(dot)com. Put "novel project" in the subject line so I don't delete without opening (my stock response to e-mail form unfamiliar sources). Thanks
