Bomber, be careful about talking to OM. I'm sure he'll try to convince you that it was all "innocent" as well, and you'll want to believe him.
Seriously...(was it saffie's idea?) just sit down with her and go through each email, page by sickening page. Eventually, her protests of innocent friendship will fade.
If they don't, then offer to print them all up and circulate them among OM's wife, his parents, your in-laws, and get their opinions.
Just make sure that you've got them all backed-up somewhere, off-site.
