Den of Thieves

1. Anonymous tip that toppled Wall Street's ring

   In 1985 an anonymous letter from Caracas told Merrill Lynch that two of its brokers were trading ahead of takeover deals. Investigators followed the trades to a Bank Leu account in the Bahamas and then to Drexel banker Dennis Levine, who pleaded guilty and gave up Ivan Boesky. Boesky secretly cooperated, paid a $100 million penalty, and implicated Martin Siegel and eventually Michael Milken, who pleaded guilty to six felonies in 1990 and paid about $600 million.

2. The cooperation chain in conspiracy prosecution

   Prosecutors unravel a conspiracy by offering each caught participant leniency in exchange for testimony against someone higher up. Each defendant's most valuable asset becomes what they know about others, so loyalty collapses one link at a time. The chain runs from peripheral players toward the central figure, whom it would be nearly impossible to reach directly.

3. Deal booms turn secrets into sellable goods

   The 1980s takeover wave meant that advance knowledge of a bid could move a stock's price sharply. That made confidential deal information worth money to anyone who could trade on it, and many bankers, lawyers and arbitrageurs held it. Siegel sold tips to Boesky for cash delivered in briefcases, which shows how bankers with a duty to clients converted that duty into private profit.

4. Technical violations reveal hidden coordinated manipulation

   Much of the case rested on offenses that sound like bookkeeping: stock parking, false records and a sham $5.3 million consulting fee that settled secret accounts between Boesky and Drexel. Read closely, these technical breaches were how concealed ownership and market manipulation were carried out. Paperwork irregularities are often where investigators find the structure of a larger fraud.
