In his article in The Times on March 14, Mr. Smith wrote of what he saw as a negative shift in Goldman’s culture, which he said had once been “the secret sauce that made this place great and allowed us to earn our clients’ trust for 143 years.”

“I am sad to say that I look around today and see virtually no trace of the culture that made me love working for this firm for many years,” he wrote. “I no longer have the pride, or the belief.”

The article exploded on Wall Street and beyond, reviving a debate about ethics and greed in the financial world. After it was published, Goldman responded by saying Mr. Smith’s assertions did not reflect the firm’s values or culture.

Publishers who are bullish on the book’s potential compared it to “House of Cards: A Tale of Hubris and Wretched Excess on Wall Street,” the 2009 book by William D. Cohan that retold the fall of Bear Stearns, or to the classic “Liar’s Poker: Rising Through the Wreckage on Wall Street,” by Michael Lewis.

There is a ripe market for books that are targeted at the business and financial communities, groups that include many affluent, highly educated book buyers.

In meetings, Mr. Smith came across as mild-mannered, polite, spare with details but sincere, publishers said. 
“He appeared to be a guy with integrity,” one publishing executive said.

But several publishers said that they had nagging concerns about the book. Among them was the thicket of legal issues that could be involved with a former employee’s writing a damning book about a large, deep-pocketed company.

One publisher said there were doubts about Mr. Smith’s ability to write an accessible narrative about his experience working in derivatives, an area that to a general reader is arcane at best. Another was skeptical that Mr. Smith, as a midlevel employee, would be able to provide enough compelling details to make the book a gripping glimpse inside a Wall Street power.

And timing may be a problem if the book is released later this year or next year, many months after Mr. Smith first leapt into the news.

“The book will likely feel dated,” an executive said. “It’s a story that had its moment.”
