Mary Alice: The most successful private investigator in Fairview was a man named Oliver Weston. Try though he might, Oliver couldn't remember the exact moment he stopped believing in love. Was it the night he caught an executive cheating with his secretary? Or was it the day he saw a housewife cheating with her delivery boy? Or was it the time he caught the girl next door cheating with the couple across the street? Whenever the moment, Oliver Weston was now officially a cynic who only believed in betrayal and suspicion. Luckily for Oliver, that's what paid his bills.
