“Is he still there?” She’d seen my gaze.

“Yes. And so’s our tail,” I added for reassurance. My protégé was behind the killer, two or three car lengths. He was not the only person from our organization on the job.

“Okay,” Alissa whispered. The woman, in her midthirties, was a whistle-blower against a government contractor that did a lot of work for the army.
