The duty guard had been seated behind a tall security glass, casually reading the sports page. He flew out of his chair as if stung by a cattle prod.

“Ma’am, I can’t leave my station,” he stuttered. “Now, calm down and tell me who are you and what this is about.”

Ann already had her identification pressed against the glass. “Call for your backup. I need all the roads out of this town closed off immediately.”

The guard noticed a general resemblance between the wild-eyed woman screaming at him and the neatly groomed female pictured on the NCIS badge. He nodded at Ann and picked up the telephone. He was still dialing when a loud screech resonated outside.

They both turned to see a speeding dark sedan swerve across the lakeshore road. From over the hill, the yellow earthmover suddenly appeared, sliding down the steep incline, apparently out of control. Ann could see it was on a collision course with the car, which the car’s driver had realized too late. In the glow from a nearby streetlight, Ann caught sight of a black-haired man in the cab of the earthmover—Pitt.

As he had staggered up the hill with a sharp pain in his left leg, Pitt had seen no other options. The gravel truck had been parked too close to the earthmover to maneuver around it, leaving the yellow mover his only option. The construction workers in this quiet town hadn’t bothered to lock either vehicle. Pitt climbed behind the controls, looked down the hill, and saw the headlights of the fleeing car already skirting the naval center. In seconds, it would pass directly below him.

Pitt depressed the clutch and slapped the gearshift lever into neutral, releasing the parking brake with his other hand. The big machine lurched forward downhill, prompting Pitt to tap the unassisted brakes. He gripped the rubberized steering wheel and tested the play. The well-used earthmover didn’t have a locking steering column, so Pitt had some maneuverability as long as he could muscle the wheel.

Glancing again down the hill, he saw the car emerge from the trees a short distance away. He had no time to waste.

Releasing the brake pedal, he let the earthmover roll forward a few feet to gain momentum, then bulled the steering wheel sharply to his right. The two front wheels turned easily, slicing through the earth at the foot of the hillside. The big steel blade scraped into the berm, slowing the mover momentarily before lurching ahead.

The ungainly machine nearly jackknifed as it tumbled over the ledge, managing to right itself with a heavy bounce. The steep hill dropped almost fifty feet, causing the mover to accelerate quickly. Pitt straightened the wheels, hoping to keep it upright. The glare of oncoming headlights filled his right windshield.
