The most recent episode of CNBC's American Greed offers an interesting and detailed look at the insider trading ring of trader Garrett Bauer, attorney Matthew Kluger, and a middleman-turned-informant named Kenneth Robinson. After a 17-year scheme that netted tens of millions of dollars (most of which went to Bauer), all three men pleaded guilty, and Kluger received the longest prison sentence ever for insider trading (12 years).

The American Greed episode lays out the key details of the lengthy scheme, and how it came undone, including:

how Kluger managed to steal information about upcoming mergers and acquisitions from the various big-name law firms he worked for;

how the trio attempted to avoid being caught by using pay phones and throwaway cell phones; creating gambling alibis by making trips to Atlantic City; and dealing in cash payments;

how a key error by Robinson combined with improved technology at the SEC allowed the agency to piece together how the scheme was set up; and

how the FBI was able to "flip" Robinson and get him to cooperate in its investigation.

The program also features several interesting audio recordings that Robinson made to develop evidence against Bauer and Kluger, such as discussions on how to clean fingerprints off of cash.
