We all know the sellers of flowers, candy, and jewelry do well on Valentine's Day, but there is another industry that does really well also. Most of us would not think of it, but private detectives live for this time of the year. If someone has a lover on the side and must divide attention on this one day, it creates a definite opportunity for those who make a living catching cheaters. One private investigator who charges $95 an hour will handle about 20 suspected infidelity cases that day. One is a doctor whose wife aroused his suspicions when she told him she would be working late on Tuesday rather than her regular daytime shift. Another is an attorney who told his wife he couldn't have lunch with her on Valentine's Day because he would be in court. She knows he always gets a lunch break from court.
The detectives say trips scheduled over the day is commonly a clue that they follow and credit card receipts for restaurants and jewelry stores are their best evidence in these cases. One detective says he was hired by a man who was going to be out of town with his wife over Valentine's and wanted to spy on his mistress. She was taped buying two Valentine's cards, buying a dress using the client's credit card, and finally going to a hotel to meet another man.
