Book excerpt: A U. S. Marshal and documentary filmmaker have evidence in their hands—and a crime ring on their trail. From the author of Undercover Jeopardy. Someone will do anything to get Mackenzie Weaver’s documentary footage—even kill her. US deputy marshal Jake Riley won’t let anyone harm Mackenzie, especially since he’s beginning to see her as more than his late friend’s little sister. But exploring their growing connection isn’t an option . . . because keeping an emotional distance is his best hope of outmaneuvering criminals determined to make this project Mackenzie’s last.
