R. Foster Winans, Trading Secrets: An Insider's Account of the Scandal at The Wall Street Journal (1986, St. Martin's Press, ISBN 0312812272) gives a full account of a young reporter's descent into temptation and insider trading. He started his career in Trenton, NJ but got his chance at the Journal, which in 1983 had older technology with tight deadlines. His problems started with a few technical slips under deadlines, and that helped set up the tempations. Life consisted of breakfast meetings and other arrangements as he wrote "Heard on the Street." His sexual orientation is a bit of an afterthought, as is his treatment of the AIDS crisis of that decade. which doesn't seem that big a deal to him.
The chapters have colorful names, like "Full Boil" and "Big Kahuna." The end came suddenly, when he got a phone call from his boss on March 1, 1984 late in the afternoon, and an SEC investigator was in the room. He was fired by a note under his door at home for "conflict of interest" and would do probation. Of course many of the other "scandals" were much larger. But it gives a good perspective on journalistic integrity and the pressures to cheat, so well David Callahan's The Cheating Culture.
