Tantalisingly, the lead story for the Mail on Sunday is the story of the story it cannot print.
It says a former royal servant has been granted an injunction preventing it from publishing the details which, it insists, are of the utmost importance and concern matters of the deepest public interest.
The paper also says there was a written demand from an un-named senior member of the Royal Family that the story should not appear.
The People has a much more straightforward tale about secrecy and royalty.
The Queen has apparently ordered every servant and aide to sign contracts under which they risk hefty financial penalties if they write revealing memoirs about royal life - as Paul Burrell has.
The main item in the Sunday Express is a claim that the French authorities want the body of Princess Diana to be exhumed, for post mortem tests.
The paper says French officials have, in effect, accused the Royal Family and the British Government of ordering a cover up.
The Express says that unpleasant though the prospect is, new tests could help end what it calls a "conspiracy industry" that has damaged the monarchy.
There is no end of advice for Michael Howard as he prepares to assume the mantle of Conservative leader.
The Sunday Telegraph remembers him as a highly unpopular, but highly successful home secretary.
Now he must help the party look outwards, it says.
Anne Widdecombe, writing in the Independent on Sunday, says Mr Howard must broaden his agenda and vision.
She wishes he had announced his candidacy not from a posh art gallery, but from a council estate.
Michael Portillo, in the Observer, says Conservatives must show they understand today's society.
Michael Howard will need to develop policies to help those who cannot opt out, he says.
The Sunday papers also turn the spotlight on the woman set to become shadow first lady.
The Mail enlists Sandra Howard's second husband, who says the former model will make the lifestyle and mannerisms of Cherie Blair seem increasingly out of place and unattractive.
And Linda McDougall, the wife of a Labour MP, tells the Sunday Times that Cherie must be shivering in her designer shoes.
