“Gotta say,” Phil spoke up, “this theory fits better with what Darby’s boss, Scott Hale, reported. I talked to him at eleven, and he swore up and down that Darby didn’t have a violent bone in his body. A tanker crew is pretty tight. You see people sleep deprived, homesick, and stressed out, while maintaining a twenty-four/seven work schedule. As an engineer, Darby got to deal with all the technical crises, and apparently big things go wrong on big ships—water in the fuel, fried electrical systems, glitches in the control software. Still, Hale never saw Darby lose his composure. In fact, the bigger the problem, the more jazzed Darby was about finding a solution. Hale certainly doesn’t believe a guy like that goes home and beats up his wife.”

“Darby was a model employee,” D.D. said.

“Darby was everyone’s favorite engineer. And apparently, quite good at Guitar Hero—they have a rec room on board.”

D.D. sighed, crossed her arms over her chest. She glanced over at Bobby, not quite meeting his eye, but looking in his general direction. “What’d you learn at the gym?” she asked.

“Brian had spent the past nine months following a vigorous exercise regimen designed to bulk up. Personal trainer swore he wasn’t doing steroids, just putting in blood, sweat, and tears. She only heard him say good things about his wife, but thought that having a state trooper for a spouse was tough on the guy. Oh, and in the past three weeks, since returning home from his last tour, Darby was definitely in a mood, but not willing to talk about it.”

“What do you mean by ‘in a mood’?”

“Personal trainer said he seemed darker, temperamental. She’d asked a couple of times, guessing trouble on the home front, but he wouldn’t comment. For what it’s worth, that makes him something of a novelty. Apparently, most clients pour out their souls while working out. Go to a gym, enter a confessional.”

D.D. perked up. “So something was on his mind, but Darby wasn’t talking about it.”

“Maybe he discovered his wife was having an affair,” Neil commented from the back. “You said when he returned, meaning, he’d just left his wife all alone for sixty days.…”

“In addition to the rec room on the ship,” Phil spoke up, “there’s a computer room for the crew. I’m working on the warrant now to get copies of all of Darby’s ingoing and outgoing e-mail. Might find something there.”

“So Tessa meets another man,” D.D. mused, “decides to off her husband. Why homicide? Why not divorce?”

She posed the question generally, a challenge to the room.

“Life insurance,” an officer spoke up.

“Expediency,” said another. “Maybe he threatened to fight a divorce.”

“Maybe Darby had something on her, threatened to make trouble if she divorced him.”
