April's Fool (Sam Cable #1)

When Sam Cable, Texas Ranger, is assigned to protect a volatile and controversial candidate for US Senate, April Marie Fortney, his life is turned into a daily dose of hell on toast. Just when he thought the situation couldn’t get worse, he wakes up next to her dead body… with no memory of how he got there.
The investigation focuses on Cable, highlighting him as the newest poster boy for an intense debate on racial relations. Racing against an impending indictment, he digs through a web of conflicting motives, politically-driven ambitions, and the past of the murdered woman, desperately seeking the truth before time runs out.
His only ally is feisty FBI agent Rita Goldman, whose sense of justice is as profound as her lack of field experience. Cable doesn’t know if the rookie agent will help prove his innocence or be the one to bury him.
