Henry Holt and Company announced Thursday that it will publish Barry Siegel's "Manifest Injustice" in January, two months earlier than planned.
Siegel is a former Los Angeles Times correspondent and Pulitzer Prize winning feature writer. He interviewed the 77-year-old Macumber for the book, which will include his release from prison.
Macumber was released this week after he pleaded no contest in a Phoenix courtroom to second-degree murder and was sentenced to time already served.
Macumber was convicted of first-degree murder in 1975 for the killings of two 20-year-old telephone company workers. He insists he didn't commit the crimes.
