In this "instantly cinematic and completely compelling" thriller (Hank Phillippi Ryan), Detective Betty has only two weeks to take down her deadliest rival—this time for good.

“The terrific adrenaline punch you’d expect for the grand finale of Kathleen Kent’s Edgar-nominated trilogy.” —Julia Heaberlin

Things are looking up for Detective Betty Rhyzyk. She’s settled into a happy marriage and been promoted to Sergeant in the Dallas Police Department. But when a hostage stand-off puts her on the phone with legendary cartel leader The Knife, things take a turn. The Knife has heard a rival is making a play for the streets of Dallas—none other than Evangeline Roy. The matriarch of a ruthless cult, Evangeline also happens to hold a personal vendetta against Betty. So who better to draw Evangeline out of hiding? Betty’s got two weeks to catch her. Or else.

With Betty’s young charge Mary Grace already missing—having left her seven-month-old baby behind in Betty’s care—and the drug dealers of Dallas donning strange red wigs and delivering cryptic messages, Betty’s in a race for answers. With the clock ticking down, it will take everything she’s got to finally put an end to Evangeline’s reign of terror, and to keep her beloved Dallas—and her own family—safe at last.
