SASKATOON - An independent publisher expects to have a book by convicted ex-wife killer Colin Thatcher on store shelves this fall.

The 440-page true-crime memoir is titled "Final Appeal: Anatomy of a Frame."

A publicist for ECW Press in Toronto says the book includes Thatcher's account of the murder and his 22 years in prison.

It also presents undisclosed evidence that Thatcher uses to question the administration of justice.

The book is tentatively set for release Sept. 1.

A jury found the one-time Saskatchewan cabinet minister guilty of first-degree murder after his former wife, JoAnn Wilson, was bludgeoned and shot to death in the garage of her Regina home in 1983.
