He nodded gloomily. ‘He’ll turn up. It’s going to be OK. They’ll find him,’ but she could hear the worry in his voice. As they walked she thought about Mac and Luke, and the friendship they’d had for so many years. Of the two of them, Luke had always had the loudest personality, Mac with his quiet dry wit the straight man to Luke’s clown. And if Luke’s love of the limelight meant he sometimes didn’t know when to quit, ensuring he was always one of the last to leave any party, Mac was invariably there to keep his friend out of trouble, bundling him into a cab when he’d had too much to drink, ensuring that he eventually made it home in one piece. Instinctively now she reached out and linked her arm through his, more grateful than she could say for his calm, steady presence. He glanced down at her and smiled, and together they walked on in silence.

She felt desolate when they returned to the empty flat. There was Luke’s leather jacket hanging on its peg; on the table by the window was a half-completed Scrabble game they’d abandoned two nights before. The last record they’d been listening to sat silent and still on the turntable. It was as though he’d stepped out only moments before, as though he might reappear at any second with a bottle of wine tucked under his arm, smiling his smile and calling her name. He hadn’t taken anything with him – not one single thing a person who was intending to leave home might take.

Mac came and stood beside her. ‘Would you like me to stay over?’ he asked. ‘I could sleep on the sofa.’

She smiled gratefully, suddenly realizing how much she’d been dreading another night alone. ‘Thanks, Mac,’ she said.

She was awoken by the sound of her intercom buzzing. Groggily she sat up, looking about her in confusion, surprised to see that she was still wearing her clothes. The fact of Luke’s disappearance hit her like a train and she gasped in distress. She remembered she’d gone to lie down while waiting for the police to come, had put her head on Luke’s pillow, breathing in the scent of his hair and skin, a feeling of utter hopelessness filling her; nervous exhaustion rolling over her in heavy waves. She must have fallen asleep.

Dazedly she stumbled to her feet and going into the living room saw Mac blinking awake on the sofa. She glanced at the clock: eight a.m. Again the intercom buzzed loudly and she hurried over to answer it. ‘Hello?’

‘Miss Haynes? DS Anderson from CID. Can I come up?’
