Pulitzer Prize-winning journalist Ronan Farrow's latest book Catch and Kill sounds like a spy-thriller filled with double-agents, double-crossing and dastardly deeds. It is all of these things, but there’s not a word of fiction in its pages.

The book tells the story of Farrow’s reporting on allegations of sexual abuse by Hollywood mogul Harvey Weinstein, and his efforts to break the story in the face of multiple campaigns to silence him.

Given that he’d been working on it for some time before publishing any reporting, Ryan wondered when Ronan knew what an explosive story he had on his hands.

"The sense of knowing that I had the goods happened very early. It’s basically from square one that women are on the record accusing Harvey Weinstein of rape."

The more evidence Farrow gathered, however, the more concerted the efforts to silence him became.

"I found myself beset by spies hired by people I was reporting on, including undercover operatives using false identities and front companies, and the sources I was working with, in this case very brave women speaking out about alleged assaults by Harvey Weinstein, were also targeted in that way. That illustrates just how far the powerful and connected will go to squash a story."

At times the story hit close to home for Ronan. Some years ago his sister Dylan Farrow accused their father Woody Allen of sexually abusing her as a child. Ryan observed that the passages in the book where Ronan reveals some of his own struggles with this history must have come at a cost to the author.

"Part of the narrative of the book is how I, for years, really struggled to outrun that very serious, very credible allegation of sexual assault … I just wanted it to go away."

Desperate to strike a blow against Farrow, Harvey Weinstein weaponized that history, even calling Woody Allen for advice on the matter. Ronan took control of his own narrative though and in the course of reporting on the Weinstein story, re-framed his relationship with his sister regarding her allegations.

"Part of the transformation I go through over the course of the plot in this book is coming to understand that I was wrong and she was right. The times over the years that I told her ‘why can’t you just shut up about this, can’t you just move on’, I was part of a system that silences women."
