Private investigators are often asked what percentage of their clients with suspicions of marital infidelity are ultimately proven to be correct. The number is actually quite high -- over 90%. Now, that does not mean (we sincerely hope) that 9 out of 10 people cheat on their partners. However, it does show that, by the time a client finds the nerve to contact a P.I., they have already logged enough suspicions and accumulated enough circumstantial evidence to ensure a very strong likelihood that there is a major problem with their relationship. Bottom line: trust your gut feelings!
