Amanda - a Would-Be Killer

This tale is about the lives of three people who became friends at university and how their lives became a nightmare.
The beautiful Amanda was torn between Harry and Simon, but was she right to marry Harry when Simon took a job in Norway?
When Simon returned from Norway, he had a great idea and went into business with Harry, maintaining the services of a major hotel group.
One night, Harry was called out as the air conditioning in their client's major hotel had failed and guests were complaining. On this visit, he saw Simon followed by Amanda coming out of a hotel suite. They were gone before he could get his wits together.
Harry finds out from the hotel's night porter that this is a regular occurrence so he sets about investigating what is going on. He sets up surveillance cameras and is dismayed what he discovers about Amanda and Simon's undercover relationship.
When Amanda is told how Simon has been using her, she sets out for revenge and her plan nearly works. At the same time Harry has found out how Simon came into money and set up a disreputable 'Gentleman's Club' where they recruited women from abroad to satisfy their members.
What follows is quite dramatic.
