She flashed her canines at him, then knocked on the door. The little dog spun in a circle, reaching new pitches of hysteria. Then, from somewhere deep inside the house, D.D. heard a male voice calling, “Thank you, Tibbie. I’m coming. Easy, sweetheart. Easy.”

A man appeared in the entryway, his frame eclipsed by the light from the windows behind him. D.D. had an impression of height, then the door swung open and he stood before them. She nearly fell back a step, catching herself at the last second and forcing herself to hold steady.

“Can I help you?” the man asked politely. He wore a thin green T-shirt stretched across rippling pecs and washboard abs. His cream linen trousers emphasized long toned legs, while a simple leather cord drew attention to his tanned neck and the shaggy ends of his sun-streaked hair.

Expensive house. Impressive man. And the smell of fresh baked bread.

“Andrew Lightfoot?” D.D. asked, her voice slightly breathless.

“Boston PD,” Alex supplied, after the man nodded. Alex shot D.D. a curious glance when she remained speechless. “Sergeant D.D. Warren, Detective Alex Wilson,” he provided. “May we come in?”

“Absolutely.” Lightfoot stepped back, gesturing for them to enter. Their presence didn’t seem to surprise him. The Harrington murders were currently front-page news. Given Lightfoot’s work with the family, maybe he’d already connected the dots and anticipated a visit from Boston’s finest.

Tibbie the dog had stopped barking, and was now running in circles around them. She stopped to sniff Alex’s ankle, then growled at D.D., then returned to Alex once more.

“Tibbie,” Lightfoot chided, not too harshly. “Forgive her. She’s a Tibetan spaniel. The breed goes back two thousand years, once serving as guard dogs for the Tibetan monasteries. Naturally, Tibbie has deeply held opinions regarding strangers.”

Lightfoot smiled at D.D., leaning forward to whisper: “She’s also a little spoiled and doesn’t care for competition from other beautiful women.” He winked, straightened, stepped away from the entranceway. “Please, make yourselves comfortable. I have just baked some croissants. I will put together a tray for us. Coffee or tea?”

“Coffee,” Alex said politely.

D.D. nodded her agreement.

Lightfoot disappeared. Tibbie stayed behind, flirting with Alex. The detective bent down, holding out his hand to the pint-sized spaniel. She sniffed his fingers carefully, then leapt into his arms and made herself at home.

“Nice doggy,” Alex said, obviously impressed with himself. He walked into the vast living space, new friend cradled in his arms. D.D. followed in his wake.

The inside of Lightfoot’s home was as impressive as the outside. The floor was covered in a gray-green slate. Lush plants softened load-bearing columns. Pale sofas and low-backed chairs formed distinct sitting areas. Mostly, however, one admired a wall of four yawning windows that overlooked the Atlantic Ocean.
