HOUSTON -- In the back seats of cars, the floors of crowded bars, tables at restaurants and even their own homes, private investigators at a Houston-area agency find infidelity.
Investigators at
K Griff Investigations & Civil Processing, Inc. have found that cheating happens anytime, anyplace and with anyone.
"You know a lot of times they will just talk and meet or meet and talk first. Then it gets progressively more and more," owner Kathy Griffin said.
"It is amazing how bold people become. Also, how amazing how flagrant people can be. (They have) just no idea they are being watched or that their spouses would suspect anything," investigator Tina DeFiore said.
Griffin has spent 15 years building a business that gets dirt on people.
"A lot of people think it is James Bond glamorous. A lot of times it is boring -- sitting in the car hours upon hours. A lot of time there is no activity, but your heart starts pounding for that one minute of video," she said.
She has video of a married man who snuck away to see prostitutes, coworkers who spent their lunch hour in the back seat of cars and a woman who cheated on her husband with another woman.
"I have always kind of looked at it like if you don't have something tangible to deal with, you can't deal with it," Griffin said.
The female private investigators have delivered on the tangible proof.
"We had them hugging and kissing, and (we're) taking pictures with our phone and everything," DeFiore said.
"We brought a video camera and acted like we had friends singing karaoke," Griffin said.
It seems easy enough -- borrow a car, grab a camera and follow your mate. So, why hire a private investigator?
In court, a private investigator with a good reputation can make a very credible witness, according to Griffin.
A man named Robert, who did not want his last name revealed, was married for 13 years.
"I wanted some proof. Anybody can say anything, but we are such a proof-driven society," he said.
A few years ago he and his wife were almost divorced when he learned he would lose full-time custody of his children.
"(The private investigation) put me in more control of the situation. It gave me a voice instead of the court dictating the way it should be," he said.

Robert did not even watch the tape that helped him win his case.
"Knowing was enough for me. I didn't want to see the guys. I didn't want to see them," he said.
Another man, "Reid," was married for four years. He hired K Griff investigators, who found his wife cheating with another woman.
"The initial shock was so devastating, I couldn't believe that it was taking place and that the first thing I thought of was that I had wasted all these years together and now it is getting thrown away for this," he said.
Reid said that trying to investigate his spouse was too hard emotionally, at first.
"When one lie turned into another and I couldn't get any answers -- that is when I started deciding in order for me to find out something, I need to do something beside using myself as checking up because it was too difficult," he said.
Houstonian "Kimberly" said she didn't need a private investigator because her husband had not cheated.
"I was thinking there is something wrong. He has had a nervous breakdown. Maybe he has got a brain tumor," she said.
On her attorney's advice, she hired one anyway. She found out that he was not only cheating, but her husband had another family and the woman was pregnant.
"When you see it for yourself, you see it on video, that it is truly your husband, the person you have been married to 20 years, then you know it is true," she said. "And you have to get through the bewilderment and shock, and once you get through that process, you have to rebuild your life."
So, how can you tell if someone is cheating?
Griffin said to listen to the nagging little voice in your head.
After doing this for years, she said that in 90 percent of the cases, there is some form of infidelity. In the other 10 percent, someone is doing something they shouldn't.
