The Infidelity Episode — Private Detective Nils Grevillius Blows It Wide Open
Welcome back to another episode of Every Day Is a Train Wreck — and today’s wreck is a doozy. Marley brings back fan-favorite guest Nils Grevillius, the private detective with 30+ years in the trenches of human chaos. Former military intelligence. Former Pinkerton agent. Author. Collector of the wildest real-life cheating stories you’ve ever heard.
If you think infidelity is just “someone stepping out,” oh honey… no.
Nils explains why the cheating is merely the symptom, and the real disease is the secret lives, hidden money, gaslighting, addiction, and psychological landmines underneath it all.
And of course — Marley gets him to spill the truly insane cases.
Including the VHS tape incident that made Marley physically gasp.
✨ Inside the Episode:
• Why some clients are a PI’s worst nightmare (“she was 40 minutes late so • she MUST be with the Clippers”)
• How infidelity connects to personality disorders — and why it’s rarely just about sex
• The real danger: hidden assets, secret bank accounts, and the “double life economy”
• How PI’s can extort the client — and the terrifying reason you must hire carefully
• The infamous case of the wife who begged to see the tape… then screamed it was staged
• When drugs and affairs overlap — and why meth turns cheating into chaos
• The denial, gaslighting, and co-dependency patterns Nils sees over and over
• What to actually do if you suspect cheating: the practical, the legal, the emotional
• How to protect yourself financially before confronting anyone
• Why some people stay in marriages long after the truth is obvious
• How to set boundaries that actually shift behavior
And yes… a conversation about Hunter Biden, Robert Downey Jr., and the difference between “can change” and “won’t change.”
It’s raw. It’s real. It’s hilarious and horrifying in equal measure.
A quintessential Train Wreck episode.
