Many questions have been asked about The Salt Path, Raynor Winn’s “unflinchingly honest” best-selling memoir, in the past week. Why exactly was the home of Winn and her husband, Moth, in North Wales repossessed?

Penguin Michael Joseph will delay the publication of The Salt Path author Raynor Winn’s next book, On Winter Hill, following an investigation in the Observer over the weekend that suggested her debut was not entirely true.

There was some serious star power in town at this year’s Karlovy Vary International Film Festival (KVIFF), with Dakota Johnson, Michael Douglas and Peter Sarsgaard making the journey to the Czech Republic for what is always a lively event.

According to a report in the Mail Online, millionaire banker and cider maker Bill Cole became a fan of Raynor Winn and Moth after reading The Salt Path. After being moved by the back, he got in touch with them without having ever met the pair and invited them to live at his historic farmhouse down in Cornwall.

An investigation by U.K. outlet The Observer has called into question the events of the bestselling non-fiction book that was adapted for the screen starring Gillian Anderson and Jason Isaacs.

Raynor Winn, author of the award-winning memoir The Salt Path, has been accused of "lies, deceit and desperation".
