Andrew Weissmann, one of the top prosecutors for Robert S. Mueller III on the Russia investigation, is writing a book that will explore his work on the special counsel’s inquiry, according to a publishing executive with knowledge of the deal.

Mr. Weissmann appears to be the first prosecutor on the special counsel’s team to make a deal with a publisher, which makes the prospect of an insider account from him especially intriguing. His book was acquired by Random House, according to the publishing executive.

Multiple executives at Random House did not respond to requests for comment.

It is unclear how much detail Mr. Weissmann will provide about the inner workings of the investigation, and whether his book will provide any major revelations. Mr. Weissmann was central to building the government’s case against Paul Manafort, Mr. Trump’s former campaign chairman. He did not conduct the investigation into whether President Trump obstructed justice, according to people familiar with the structure of the Mueller team.
