Who's Grace?

Fast paced murder mystery with a twist. A Christian magazine editor named John Smyth witnesses a murder through the window of an airplane as it descends for a landing in Winnipeg, Canada. Neither the city police nor the RCMP (Mounties) take his tip seriously until an unidentified woman's body turns up in some nearby woods two weeks later. The only clue to her identity is a necklace with a pendant bearing the name 'Grace.' Who is she, and where is her killer? As the case twists and turns, everyone involved gets to see clear evidence of the grace of God.
