MOOSE JAW, Sask. - Convicted wife killer Colin Thatcher says he doesn't think a new Saskatchewan law that prohibits profiting from recounting crimes applies to his new book.

The Saskatchewan government rushed through legislation in May that is meant to stop criminals from keeping the money if they sell their crime stories.

But Thatcher says his new book is different because it's not a recollection or a retelling of the 1983 murder of his ex-wife, JoAnn Wilson.

Thatcher says the book -- titled "Final Appeal: Anatomy of a Frame" -- is about his arrest and more than two decades spent dealing with the justice system.

The former Saskatchewan cabinet minister who spent 22 years behind bars also says he didn't write the book for profit, but to assert his innocence.

Saskatchewan Justice Minister Don Morgan acknowledged this week that provincial officials have not yet read the book, but said it's his expectation that the law will apply.
