ONE of Scotland's leading authors is courting controversy six months before his novel inspired by the Lockerbie bombing hits bookshelves.

James Robertson has been condemned by US relatives of the Lockerbie victims as being part of a "cottage industry of deniers".

The Professor of Truth, due to be published in June, tells the story of a university lecturer who feels deprived of justice after his wife and daughter were killed in the bombing of a plane over Scotland 21 years earlier.

It echoes the real-life story of Dr Jim Swire, whose 23-year-old daughter Flora was one of the 270 people killed in the 1988 terrorist attack.

Last year, the author delivered a lecture entitled The Lockerbie Affair and Scottish Society at the Edinburgh International Book Festival, spelling out why he believed Abdelbaset Ali Mohmed Al Megrahi, the only man convicted of the atrocity, had suffered a miscarriage of justice.

Frank Dugan, president of the US support group Victims of Pan Am Flight 103, said: "If the book is inspired by the Lockerbie bombing and the author believes Megrahi was not guilty I am afraid it will not rise to the top of my reading list."
