Query: OMERTÀ ON TRADING SECRETS

A hot contender for the title of worst trading book ever written. Rather than a discussion of the one issue that might lead one to respect the author - his trading - he subjects his readers to 200 pages of whingeing about his victimization on account of his father's mafia connections. While Mr. Borsellino goes to extraordinary lengths to deny that he has maintained these, he produces such a mind-numbingly tedious volume that one begins to wonder whether its publisher took the decision to publish on the basis of an "offer he couldn't refuse".
