If you even suspect your spouse is cheating on you, you're probably right, says Mike Lewis, lead investigator and owner of Confidential Investigative Services. In 85 percent of the cases he investigates, someone is skanking around town. Almost always, the other woman (or man) is a co-worker. Since 1997, Lewis has trailed and photographed Cleveland adulterers in their natural habitats - parking garages, hotels, the Metroparks - anywhere someone can grab a little booty on the DL. Recently, he worked a case in Richmond Heights involving a millionaire philanderer who was leading a secret double life with a call girl. Now, his evidence will be used in divorce court. A blue-collar Bruce Wayne, Lewis stocks up on state-of-the-art gadgets to use against evildoers during his nightly stakeouts. He has GPS discs he can slip under a car's bumper and a camera that can capture someone making out in the cab of a truck 500 feet away - in the dark. His services are a bit steep - $600 to start - but that's chump change, when you consider the alimony you'll be getting.
