The publisher of EL James' latest erotic novel said it will continue to investigate the theft of a copy of the unpublished book despite police saying there was "no evidence" a crime was committed.
The new book, called Grey, is a re-telling of the first novel in the hit sadomasochistic saga about an affair between mysterious tycoon Christian Grey and lover Anastasia Steele from the point of view of its title character.
It made headlines last week ahead of its publication tomorrow when it was reported a finished copy had been stolen.
But a spokeswoman for Kent Police said: "Following a report that one book had been stolen after packaging was found to be damaged, there is no evidence at this stage to suggest that an offence has been committed. No more action will be taken unless further information is received."
A spokeswoman for p ublisher Penguin Randomhouse said: "We are delighted that the book's theft does not appear to have been for any malicious intent or financial gain. We can however confirm that we will continue our investigations into this matter and that we will be reporting any findings to Kent police.
"We're hugely excited to be publishing Grey by EL James tomorrow."
EL James' fans can get their hands on the latest story at the stroke of midnight tonight.
The new book will be in shops tomorrow but is available to download on Kindle from midnight and is already among Amazon's eBook best-sellers.
Its author is in New York on publication day as part of an international publicity campaign for the book which is a guaranteed best-seller.
Jamie Dornan played Grey and Dakota Johnson was his lover in the hugely successful film version of the story.
James said she wrote the book after demand from fans. On the opening page, she says it is "dedicated to those readers who asked ... and asked ... and asked ... and asked for this".
The Fifty Shades trilogy - Fifty Shades Of Grey, Fifty Shades Darker and Fifty Shades Freed - has sold more than 125 million copies around the world.
It has made James a millionaire many times over. This year's Sunday Times Rich List estimated her fortune at £75 million.
