Ha. Considering people in affairs tend to lose about 40 I.Q. points, right off the top, you might be being generous here.
In the midst of my wife's affair, I caught her once red-handed, hooking up with her OM at a friend of his' house. I had hid a prepaid cellphone in the trunk of her car, in our son's baseball gear bag, and installed a GPS app on it, that would send me emails. I also had a voice-activated recorder velcro'd underneath the front seat of her BMW, and as painful as all of this adultery was, I did have to laugh later on that night when I listened to the voice recorder as I was offloading it onto my laptop archives.
The illicit couple were trying to figure out how I knew they were at that house, hooking up. OM was trying to sound all smart, and says to my wayward wife "Well, it's probably thru that BMW Assist that you have on the car," like some know-it-all. My wife immediately agreed, too, even though you have to have a police report (with case number!) in order to EVER get info on a car's whereabouts from BMW! And even if you didn't know about the ol' GPS-app-on-the-prepaid-cellphone-in-the-trunk Trick, who's to say I didn't just, you know, FOLLOW them or something???
