A reminder of the process:

It doesn't seem likely there will be a detailed investigative narrative presented to the public similar to the multi-tome report produced by Independent Counsel Kenneth Starr back in 1998.
Mr Starr's wide-ranging investigation that started with a real-estate inquiry and ended up scouring Bill Clinton's affair with Monica Lewinsky was governed by a federal statute with different rules. And Mr Starr himself - a former judge and Republican administration lawyer - was a different kind of man to the by-the-books ex-Marine Mueller.
Mr Mueller's probe is conducted under the auspices of the Justice Department and is governed by its regulations.
The special counsel's obligations at the conclusion of his work are to provide a "confidential report" to Attorney General Bill Barr explaining his prosecutorial decisions.
Mr Barr must then provide the top members of the Senate and House Judiciary committees with a brief explanation of any actions taken - or instances where he overruled the special counsel's proposed action.
It is up to the attorney general to decide whether it would be in the "public interest" to make any of these reports or communications accessible to the rest of us.

Up until now, Mr Mueller has spoken through his court filings, which are rich in detail and new revelations. While Mr Mueller's report to the attorney general will be confidential, it may not be his final word at the conclusion of his investigations.
The special counsel could be building a prosecutorial path that leads to the White House, with the final stones about to be set. Court-watchers note multiple sealed indictments have been filed in the federal courts used by Mr Mueller's team over the past few months. Those could be political and legal bombs, with their fuses lit.
