Deadly Appearances (2000)

Joanne Kilbourn, ex-detective turned university lecturer, is still haunted by the unsolved murder of her politician husband, Ian. At a fund raiser picnic thrown by her husband's old running-mate, Andy Boychuk, Jo and her old partner Millard overhear Andy arguing with a young woman who claims he is the devil. When the woman turns up dead later that night, Andy is Millard's chief suspect. Jo must determine whether or not her friend is guilty, and get to the truth behind the murder. Meanwhile, she continues to try to help her three children deal with the death of their father, and to integrate her newly adopted daughter, Taylor, into the family.
