From New York Times and #1 international bestselling author Linwood Barclay comes the jaw-dropping finale of the Promise Falls Trilogy.
 
It’s May 23, and small town Promise Falls finds itself in the midst of a full-blown catastrophe with dozens dead from a flu-like virus. Investigator Cal Weaver quickly zeros in on mass poisoning and a tainted water supply.
 
Meanwhile, a college student has been murdered, and Detective Barry Duckworth recognizes a killer’s handiwork from the unsolved homicides of two women in town. Suddenly, the strange events from the last month start to add up: Bloody mannequins in car “23” of an abandoned Ferris wheel, a fiery, out-of-control bus with “23” on the back, “23” on the hoodie of a man accused of assault.
 
The motive for hurting the people of this town points to the number 23 --- and working out why will bring Duckworth closer to death than ever before.

Audiobook available, narrated by Richard Poe and Brian O'Neill
