Sitting on the running board and collecting himself, he observed the scene of chaos around him. Sirens blared as dozens of disheveled lab workers wandered around in a daze. Smoke still rose from the building, though fire had thankfully not materialized. Taking it all in, Pitt somehow had an odd sense that the explosion was no accident. Rising to his feet, he thought of Lisa as he gazed at the damaged Auburn, then felt a pang of anger gradually swell from within.

STANDING BEHIND A ROW of hedges across the street, Clay Zak watched the mayhem with idle satisfaction. After Lisa’s ambulance roared away and the smoke began to clear, he walked several blocks down a side alley to his parked rental car. Unzipping a gray jumpsuit, he tossed it into a nearby trash can, then climbed into the car and cautiously drove to Reagan National Airport.

LOW MIST HUNG OVER THE STILL WATERS SURROUNDING Kitimat as the first gray swaths of dawn streaked the eastern sky. A distant rumble of a truck rolling through the streets of the town drifted over the water, breaking the early-morning silence.

In the cabin of the NUMA workboat, Dirk set down a mug of hot coffee and started the boat’s engine. The inboard diesel sprang immediately to life, murmuring quietly in the damp air. Dirk glanced out the cockpit window, spying a tall figure approaching on the dock.

“Your suitor has arrived right on time,” Dirk said aloud.

Summer climbed up from the berths below and gave her brother a scornful look, then stepped onto the stern deck. Trevor Miller walked up with a heavy case under one arm.

“Good morning,” Summer greeted. “You were successful?”

Trevor handed the case to Summer, then stepped aboard. He gave Summer an admiring look, then nodded.

“A lucky stroke for us that the municipality of Kitimat has its own Olympic-sized swimming pool. The pool maintenance director willfully parted with his water quality analyzer in exchange for a case of beer.”

“The price of science,” Dirk said, poking his head out the wheelhouse door.

“The results obviously won’t be on a par with NUMA’s computer analysis, but it will allow us to at least measure the pH levels.”

“ That will give us a ballpark gauge. If we find a low pH level, then we know that the acidity has increased. And an increase in acidity can occur from elevated amounts of carbon dioxide in the seawater,” Summer said.

Summer opened the case, finding a commercial-grade portable water analyzer along with numerous plastic vials. “The important thing is to replicate the high acidity readings identified by the lab. This ought to do the job for us.”
