The Pledge (Detective Betty, 3)

In this electric conclusion to the Edgar-nominated trilogy, Detective Betty has only two weeks to take down her deadliest rival--this time for good.

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.
