Great book by the late Robert Friedman,I have it in 6 parts,and makes for fascinating reading.Interesting to note on the second wave of mobsters that came to America as related to Project Hammer,although Friedman does not make note of it.Hope you enjoy this quick read....

[.....I had just returned from a vacation in June 1998 when I found out how dangerous it is to investigate the Russian mob. Mike McCall, a top agent on the FBI’s Russian Organized Crime Squad in Manhattan, called me with chilling news. “I hate to be the bearer of bad tidings,” he said gently, “but the FBI has reliable information that a major Russian organized crime figure has taken out a contract on your life.”

Belgian journalist Alain Lallemand, an expert on Russian organized crime who has suffered through hair-raising attempts on his life, once told me that the Russian mob would leave journalists alone as long they didn’t come between the mobsters and their money. In a series of revelatory articles about the growing threat of the Russian mob in such publications as New York, Details, and Vanity Fair, I had apparently crossed this dangerous line.

Stunned, I finally managed to ask McCall what I was supposed to do in response. “We are working on this just as hard as we can,” he answered, “but right now we can’t preclude the possibility of something happening to you, okay?” But how could I protect myself—and my wife? McCall bluntly replied that it wasn’t the FBI’s responsibility to offer that kind of advice. After some pleading, he at last offered a tip: “If you have the opportunity to lie low,” he said simply, “take it.”

At the time, I was getting ready to fly to Miami to interview a Russian crime lord nicknamed Tarzan, a man who had sold Russian military helicopters to Colombian drug barons and was in the process of brokering a deal to sell them a submarine, complete with a retired Russian captain and a crew of seventeen, when he was arrested by the Drug Enforcement Agency. McCall told me to forget about the trip to Miami, which has the second largest concentration of Russian mobsters in the United States; a hit man could easily trace me to my South Beach hotel. For that matter, he said, I should also forget about doing any more interviews in Brighton Beach, Brooklyn—ground zero for the Russian mob in America. In fact, he advised, I should consider forgetting doing any more reporting at all on the subject.

The next day, a magazine that had just published one of my expose's of the Russian criminals generously supplied me with some getaway money and a bulletproof vest. Before I could flee town, however, I noticed a thickly bearded, muscular Russian loitering around my apartment building whom I was certain I had once seen in the company of a notorious Russian don nicknamed Fat Felix. I didn’t waste any more time. I quickly collected my wife and drove up to a rented hideaway in Vermont......]
