Schapelle Corby's insistence she knew nothing about the bag of marijuana found in her boogie board bag has been dealt another major blow with a new book detailing where the marijuana came from, how it got into her bag and her father's 30-year history of drug dealing.

Sins of the Father by Sun-Herald journalist Eamonn Duff adds myriad details to the circumstances surrounding one of Australia's most polarising criminal cases since Lindy Chamberlain's conviction.

Launching the book this morning, Allen & Unwin publisher Richard Walsh said: "Indonesians have said from the beginning she's a guilty person, we are saying to a domestic audience we agree."

The book fills in many of the gaps in other accounts to argue that Mick Corby was running drugs across Australia and to Bali and had been involved in selling drugs for most of his life.
