Decker rapped as hard as he could on the wood with a gloved hand. Behind the wall, an elderly voice said, “I hear you, I hear you.” A moment later the door opened and a gush of hot air blasted their faces. “Detective Sugar?”

“Yes, yes. Come in.” He left the door open, turned his back, and shuffled across the mudroom floor and into the living room. The men followed. Sugar said, “Hope you found the place okay. The addresses can be confusing.”

“No problem.” Decker wiped his boots assiduously on the floor mat and dried them off with a provided towel. McAdams did the same. “Great house.”

“Courtesy of a spinster aunt who willed it to me fifty years ago when the area wasn’t hoity-toity and the roof leaked like a sieve. I almost sold it after my wife died. Thank God I didn’t. The bluebloods next door are after me to sell it to them for some ridiculous price. You want some tea?”

“That would be great. Thank you for seeing us.”

“Yes, yes.” Sugar was around five five, with stooped shoulders, white hair, milky blue eyes, and a bony frame. He wore a thick cable-knit sweater and wool pants. Argyle socks covered feet that were tucked into slippers. “Sit anywhere you’d like.”

Decker chose a green-and-red plaid sofa that matched two green-and-red plaid chairs. McAdams took a chair. There were coffee table and end tables made from particleboard and originally stained in a deep espresso brown. Over the years—more like decades—they had suffered chips, scratches, and gouges where the lighter board was showing through. The floor was pine, covered in part by an area rug worn thin with use. Heat was pouring out of the radiator, and the flat-screen television—Sugar’s nod to modernity—was on some kind of a game show.

When Sugar returned from the kitchen, he set the tray down on the living room table. He turned off the TV and turned down the heat. He poured himself a cup of tea. “Make it how you like it. I’m not a waiter.”

Decker poured hot water into two mugs—for McAdams and for himself. After he made the introductions, he said, “How long were you with the Marylebone PD, Detective Sugar?”

“It’s Allan and I was with them for thirty years. Wish I’d come up when you did, with AFIS and CODIS and all that razzamatazz. You don’t even have to work anymore. Just plug in fingerprints or DNA and the machines pop out the answers.”

“It’s been a boon,” Decker said.
