When I find evidence of someone cheating, I remain covert. It’s not my job to challenge them; I try to remain completely neutral and don’t let my emotions come into my work. I’m there to gather the evidence for my clients, and it’s up to them how they use it.

Once, a client asked to join me to watch her husband exit a hotel with his girlfriend. It’s not something I normally allow, and I advise against it, but she insisted on being there. When her husband emerged from the hotel, my client got out of my car and confronted him; after the commotion died down, she was so upset that I had to give her a lift home. If you do hire a private investigator, it’s important that you’re not afraid of change. I see that a lot: clients who choose to bury their heads in the sand after their partner’s infidelity is confirmed, rather than face up to the reality of what’s happened.
