As year after year passes, EPIS investigators, come across cases where the client have either neglected to accept the idea that their spouse is a very alert and aware of infidelity or they have completely underestimated their spouse or lover.

Many of the techniques used by private investigators who concentrate in this type of occupation are known to the cheater. They know how to look for surveillance or a tail when traveling to meet their lover. They will be cautious with their home computer which might be monitored. They know that phone numbers can be traced. This makes it vital that you do not give them any reason to be more watchful or attentive.

From all these years of conducting Infidelity Investigation, we have the following list of tips that we think it will advice to cheaters to aid them in keeping their infidelity hidden.

The clever cheaters will often do the following:

• Never meet in a place where they cannot park and walk to someplace legitimate as a cover story. 
• They usually don't get involved with someone you (the spouse) know.
• They are always watching for a tail to see if someone is following them. They make frequent stops and sudden turns and drive extremely slow, just watch traffic.
• Never use a credit card.
• Cancel the *69 option on the land line telephone.
• Never store phone numbers in their phone or write them down. If they do write them down, they will do it in a "code" to hide the real number.
• They usually don't have caller I.D., or if they do, they will cancel it and switch the cellular telephones to blocked number.
• They will clear the phone call history regularly.
• They usually meet at different locations, where the possibility of seeing a co-worker or friends is none.
• They usually take a shower immediately when returning home or they will cover it up with cologne or exhaust fumes.
• They tend to change the passwords of the cellular phone more often and also using a pre-paid calling card, so the numbers doesn't get registered.
• They might get their friends involved to cover their story.
• The more smart ones will have the lover page them with a wrong or disconnected number, so a suspicious spouse cannot determine who had called.
• And the last, they will never admit to anything.  They deny everything. Unless you're caught in the act of having intercourse, deny, deny, deny. Most people are more than happy to live in a state of denial; your SO would rather believe you than admit to herself the terrible truth. So deny as much as is plausible, and then some.
