Chapter 1

      His neck was really beginning to ache.

      It amazed him how these last ten years, after steadily climbing up the ladder, from cop to detective to Secret Service agent, Nick Sheffield found himself right back where he started: doing grunt work. There was no other accurate way to describe it: remaining stationary, hour after hour, waiting for a perpetrator to finally show up—provided he did show up, which was never a sure thing.

      But, at least for now, Nick had no other recourse, no other trail to pursue. This lonely ranch was where the evidence had led him.

      He’d always hated surveillance work. Ever since he’d been a young kid, patience had never been in his nature. He was much happier being active. Doing something instead of just standing as still as a statue, feeling his five o’clock shadow grow.

      However, in this particular instance, it was unavoidably necessary. He had no other way to capture his quarry.

      Nick supposed he should consider this a triumph. After all, less than twenty-four hours ago, he still hadn’t a clue where all those threatening letters and e-mails aimed at the man whose life he was to safeguard, Senator Joe Colton, came from. These days, it seemed like every crazy malcontent and his dog had access to a computer and the Internet, which made tracking down the right crazy malcontent one hell of a challenge. One that fortunately, he was more than up to—with a healthy dose of help from the reformed computer hacker, Steve Hennessey, who now worked for his security staff.

      Technically, it was the Senator’s staff, but he ran it. Handpicked the people and ran the staff like a well-oiled, efficient machine ever since he’d been assigned to the Senator. He liked to think that he was doing his bit to help the Senator get elected to the highest post of the land.

      There was no doubt in his mind that unless something unforeseen or drastic happened, the Senator would go on to become the next President of the United States. In his opinion, and he’d been around more than a little in his thirty years on earth, there was no other man even half as qualified to assume the position of President as Senator Joe Colton.

      He didn’t just work for the Senator, he admired the man, admired what he stood for and what he hoped to accomplish once elected. In the last few months, he’d seen Senator Colton up close and under less-than-favorable conditions. In his opinion, they just did not come any more genuine—or charismatic—than the Senator.

      Nick doubted very much if he would have spent the last eight hours standing behind a slightly open barn door, watching the front of an unoccupied, ramshackle ranch house for anyone else.

      Damn it, where the hell was this creep? Was he going to show at all?

      He didn’t want to have to do this for another hour, much less entertain the prospect of doing it for another day.

      Nick’s temper was getting frayed. It was late and humid, and the mosquitoes kept trying to make a meal out of him. He waved another one away from his neck even as he felt sweat sliding down his spine, making the shirt beneath his black jacket stick to his skin. Talk about discomfort.

      Nick blew out a frustrated breath.

      Why couldn’t this crazy be located in one of the major cities, living in a high-rise apartment? Why did it have to be someone who lived the life of a hermit? The IP address that Steve had miraculously tracked down had brought him to a town that barely made the
