in the summer of 2003, jonathan nyce's marriage was falling apart. he had been pushed out of the pharmaceutical company he founded and was playing mr. mom to the three children he had with michelle. dr. nyce, oblivious, he says, to his wife's regular hookups with the gardener at hot sheets motels, claimed he received a threatening phone call. >> it was horrific. it was a man basically saying, i have something you need to listen to. and then he played the tape of michelle having sex with someone else. >> how did you know it was michelle? >> if you ever heard my wife speak, you would know her voice is very distinctive and the man called her by her name in the tape, so it was very clear that it was michelle. >> the mystery caller, nyce says, hung up and immediately rang again, now demanding $500,000. $500,000 or else what?
