Blake rushes McCann book

John Blake Publishing is to release an unauthorised book about the disappearance of ­toddler Madeleine McCann at the end of the month.

Managing director John Blake said he had been forced to double his initial print run as a result of “massive orders” for Vanished: the Truth About the Disappearance of Madeleine McCann, which author Danny Collins based on interviews with friends and close contacts of the McCann family.

Blake believes there would be similar interest in a book written by the McCanns themselves, which is reportedly in the pipeline. “I think there is likely to be a massive amount of interest out there. It’s a terrible, awful story, but it’s one that has captured people’s curiosity.”
But although Kate and Gerry McCann are reportedly planning a ghostwritten tell-all memoir, their spokeswoman said the couple had not yet agreed to any project.

“Reports of a confirmed book deal are incorrect,” she said. “We continue to be approached by various people, and we may consider these offers at some point in the future, but for now there is no deal in place.”
