In spite of her intention to scan methodically every inch of the body and its surroundings, her eyes were irresistibly drawn to the crusted blood surrounding the raw wound. The exposed flesh looked like meat left unwrapped overnight on a kitchen counter. As she realized what she was seeing, Marijke’s stomach gave an unexpected lurch. From a distance, she’d made the same assumption as Maartens. But de Groot hadn’t been castrated. His genitals were still attached to his body, albeit smeared grotesquely with blood. She sucked in a mouthful of air.

Whoever had killed the psychologist hadn’t removed his sexual organs. His murderer had scalped his pubic hair.

Carol leaned on the window sill, the steam from her coffee making a misty patch on the glass. The weather had closed in overnight, and the Firth of Forth was a rumpled sheet of grey silk with slubs of white where the occasional wave broke far from shore. She longed for her familiar London skyline.

It had been a mistake to come here. Whatever she’d gained professionally from the trip was more than cancelled out by the rawness of the emotion that Tony’s presence had stirred up in her. Bitterly, she acknowledged to herself that she had still been clinging to a sliver of hope that their relationship might finally catch fire after an appropriate gap of time and space. The hope had crumbled like a sand-castle in the sun with his revelation that he had moved forward, just as she had always hoped he would. Except that she wasn’t the companion he had chosen to share the journey with.

She hoped she hadn’t let the depth of her disappointment show as they’d left the pub, forcing her face to smile the congratulation of a friend. Then she’d turned away, letting the sharp north-easterly wind give her an excuse for smarting eyes. She’d followed his car up the hill away from the picture-postcard harbour to the small hotel where he’d arranged a room for her. She’d taken a defiant ten minutes to repair her make-up and arrange her hair to its best advantage. And to change out of her jeans into a tight skirt that revealed more than anyone in the Met had ever seen. She might have lost the battle, but that didn’t mean she had to beat a bedraggled retreat. Let him see what he’s missing, she thought, throwing down a gauntlet to herself as much as to him.
