Stride ran his hands back through his wavy hair and blinked to stay awake. He was tired and cold. The temperature hovered around zero, and here on the high hillside, the lake wind hit his skin like acid. They’d already spent two hours outside this evening, up on the arch of the Bong Bridge that connected Duluth to its Wisconsin twin port town, Superior. A semi had spilled over on the icy bridge deck, closing the span and stranding cars for hours. One woman freaked out at the height and began threatening to throw herself into the water. A typical January evening.

He’d barely had time for a hot shower at home when Maggie called about the murder of Jay Ferris. Now he was cold again, but in Duluth, the chill of winter never really went away. You lived your life cold. Even under a wool blanket, your bones never forgot the cold. They reminded you with a little involuntary shiver.

Stride stood with Maggie next to his Ford Bronco, which was crusted with dirt and road salt. He studied the street and the house. His team had already closed off the scene, and it was remote enough and late enough – after midnight – that news of the murder hadn’t leaked to the media yet. That wouldn’t last long, particularly given the prominence of the husband and wife involved in the crime.

The road banked sharply downward from where he was parked. The street was free of snow, but six-foot drifts had been piled on the shoulders by the plows. There were three houses here, all on the cliffside overlooking the lake, all worth in excess of a million dollars. He knew the families who owned them. Janine and Jay. Next to them, another surgeon, along with his gay partner and their three adopted children. Next to them, behind a wrought-iron gate, the owners of a successful restaurant chain located in the tourist heart of the city in Canal Park. Duluth’s upper-crust was a small community, and the chief made it a point that he and his lieutenants keep good relationships with them.

‘I want you to interview the neighbors yourself,’ he told Maggie.

‘Sure.’

‘Be polite.’

‘Me? I’m always polite.’
