The pledge

Summary: "The third and final installment in Detective Betty Rhyzyk's story. Things are looking up for Detective Betty--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 the legendary cartel leader The Knife, things take a dangerous turn. It seems a rival cartel is making a play for business in Dallas--headed by none other than Evangeline Roy, not only the matriarch of a ruthless cult, but a woman who has been nursing a personal vendetta against Betty for years. The Knife wants Betty to get Evangeline out of Dallas. Or else. Within days, law enforcement is picking up drug dealers wearing strange red wigs, all bearing cryptic messages for Betty, and Mary Grace, the young woman Betty's been helping to find her feet, has disappeared--leaving her seven-month-old baby behind. With the clock ticking down, and as Evangeline draws closer and The Knife's patience wears thin, it will take everything Betty's got to put an end to Evangeline's reign of terror, and to keep her growing family and beloved Dallas safe"--
