“Just making conversation.” D.D. continued to study the man. She pegged his age for early forties, which was uncomfortably close to her own, given that he’d just referred to himself as a dinosaur. He wasn’t too tall, maybe five eleven, still relatively trim. His short dark hair was liberally sprinkled with silver, and his blue eyes crinkled at the corners when he frowned. A working man’s George Clooney. She could appreciate that.

So, Alex Wilson from Amherst. She’d have to ask around.

“All right, Professor. What else do you have to show us?”

“I think it started with the wife.” Alex led them down the hallway, keeping to one side in order to avoid the blood trail. “Maybe they started arguing at dinner, dunno. But he followed her into the bedroom, got her from behind. This one was quick. One hard blow, severing the spinal column at the base of the skull. Even if she lived long enough to scream, the blow would’ve paralyzed her. She went down on her knees, her heart stopping before she bled out.”

Alex passed through a doorway on the right. D.D. found herself in a fairly large bedroom furnished with a king-size mattress and two mismatched dressers that looked as if they’d been picked up at a rummage sale. The bed was topped with an old flowered quilt. Two pink-colored sheets served as curtains over the windows.

On top of the largest dresser sat an assortment of framed photos, including an eight-by-ten of a smiling sandy-haired bride and grinning dark-haired groom. On the floor in front of the dresser was a conspicuously large dark stain covering at least a dozen floorboards. What was left of the sandy-haired bride, presumably.

“Where’s the body?”

“You’ll see,” Alex said. He led them back into the hall, stepped gingerly over the blood spatter and into the next bedroom. This one was smaller and painted a rich blue. Posters of Tom Brady peppered one wall, while rows of shelving containing signed footballs and various sports trophies covered the others.

To the right, a twin mattress bore a Patriots-themed comforter. Directly ahead stood a card table that appeared to serve as a desk, with a metal chair half pushed back. Beside the chair, on the floor, loomed another dark stain.

“Oldest son,” Alex supplied. “Maybe he heard the disturbance in his parents’ room. Stood up to take a look. To judge from the trophies, the kid’s athletic and he’s a decent size for his age. After the mom, the next logical threat. So the subject entered the room quickly and decisively. Kid’s probably still thinking, What the hell? when the subject catches him in the side, slicing between the ribs, straight into the heart.”

“Single blow again?” D.D. asked sharply.

“These two, yes.”

“First in the back of the neck, then between the ribs. I’m thinking the subject has had some training,” she said.
