Free, how did Germany do when it had to fight Russia and the United States on two different fronts? The OM needs to feel some heat at home. Voice activated recorders in the car are great. If she talks to him on the phone you may get his first name. From that you can go to company directory and narrow it down. You can search his first name and the company name, check images and see if you see his face. When you get his name it's all over. Can you check phone records? If you record her you are going to hear a lot upsetting thoughts. Remember she is deluded right now and it's not forever. Can you get photo's of them holding hands, kissing? Give that to the OM's wife and he'll have to sleep with one eye open.
Take your time and think your actions through. It get's a lot harder if she is suspicious. The turtle wins the race, be slow and steady.
