As far as Romy Juneau was concerned, she would only ever have met Ben on the single occasion they’d bumped into one another in Rue Georges Brassens. She was oblivious of their second encounter, and always would be, because she was lying sprawled on the Persian rug inside her living room with a broken neck. That much Ben could tell at a glance from the unnatural angle of her head to her body.

He stood frozen in the doorway for an instant. He had seen many dead people before now. But never quite in such circumstances. His shoulders dropped and something tightened inside his throat at the pathetic sight of her lying there. The leather satchel she’d been carrying earlier had been emptied and left lying along with its contents on the rug a few feet away.

He went over to her and knelt next to the body. She was very still, with that special quality of inertia that only death can confer on a person. If there had been any blood, it would have been easy to see against the white cashmere top she was wearing. It looked as though a single strike to the neck had killed her. Ben looked around him for any kind of impact weapon, but there was nothing. A very strong man could have done it using his bare hands, but it would have taken a blow of tremendous force.

Her eyes were open and staring sightlessly straight at him, the vividness of their colour faded like the wings of a dead butterfly. Ben reached out and laid two fingers on the side of her throat. He had expected no pulse and found none. Her soft skin was still warm, also expected, because this had happened to her only minutes ago. While she’d been waiting for her coffee to brew.

Her death touched Ben deep, though he didn’t know why. It was as if he’d known her, somehow. As if part of his mind was trying to reconnect with an old scrambled memory lost somewhere in the murk of the dim and distant past. It was a strange feeling.

He lingered next to her body for a couple more seconds, then stood up and walked grimly to the living-room window. It was the archetypal Parisian floor-to-ceiling iron window with the ornate knobs and designer rust, flanked by gauzy white drapes. It overlooked the same side of the building as the kitchen. He looked out at the street below. The carpenters had finished fixing the plywood to the bookshop window. Cars, vans, bikes were passing by on the road, pedestrians strolling along the pavements, normal city life going on as usual.

And up here on the floor behind where Ben was standing, a young woman with a snapped neck.
