“Kaiser” is John Kaiser, a former FBI profiler who helped solve New Orleans ’s biggest serial murder case, in which eleven women disappeared while paintings of their corpses turned up in art galleries around the world. Kaiser is the Bureau’s point man on the NOMURS task force.

“The scene’s more crowded than it should be,” Sean says softly. “Piazza’s in there. Plenty of tension, if you’re looking. But that’s not your problem. You’re a consultant. That’s it.”

“I’m ready. Let’s do it.”

He opens the door to a gleaming world of granite, travertine, shining enamel, and pickled wood. Kitchens like this always feel like operating rooms to me, and this one actually has a patient in it somewhere. A dead one. I sweep my eyes over a blur of faces and nod a greeting. Captain Carmen Piazza nods back. Then I look down and see a blood trail on the floor. Someone has crawled or been dragged across the marble floor to a spot behind the island at the center of the kitchen. Dragged, I decide.

“Behind the island,” Sean says from my shoulder.

Someone has set up a floodlight. When I round the island, I see a stunning Technicolor image of a naked corpse lying on its back. The details of the upper body hit me in a surreal rush: livid bite marks on the chest, bloody ones on the face, one bullet hole in the center of the abdomen, a contact gunshot wound to the forehead. The superfine blood spatter of a high-speed-impact wound has dotted the marble tiles like a monochrome Pollock painting behind the victim’s head. Arthur LeGendre’s face is a frozen shriek of horror and pain, shocked into permanence when part of his brain was blown out through the back of his skull.
