Scotland Yard Detective Inspector Mick Chandra is faced with his most challenging case: how to break up a cult preying on middle-aged wealthy people by promising them that "death is the ultimate goal" to a happy new life. Specifically, Mick is challenged to solve the suicide of Rosalinda Evelyn, a beautiful, successful 46-year-old actress who unaccountably committed suicide. Her daughter suspects a "self help group" her mother had recently joined, that preaches death as a solution to all pain. Mick knows that the Oracle of Baal is a cult, not a self-help group. But how to prove it? This is the fourth book in the Mick Chandra mystery series.
