Ribbon of Death — J.B. Davis

Set against the backdrop of the sweltering, Arizona monsoon season, Ribbon Of Death offers a complex puzzle eventually revealing a conspiracy of international proportions.
Once again Mary Beth Perkins and her sister, Martha, become involved in the intrigue as they journey to the side of their dying mother.
Two apparently unrelated deaths, attributed to natural causes, capture their attention. A New York detective, who has his own reasons for suspecting foul play, joins them in a search for the truth.
The investigation exposes the grave consequences of excessive greed, and eventually unearths a grim specter from the past.
In any murder mystery good always triumphs and evil is ultimately punished-maybe.
