Logan pressed the mobile against his chest. ‘Slow down! I said I wanted to go up to the hospital, not end up in bloody A&E.’ Then back to the phone. ‘What do you mean, he’s not there? ’

A small pause. Then Sergeant Big Gary McCormack’s bunged-up Aberdonian accent grumbled down the line. ‘What do you think I mean? I mean, he’s not there. Sent a car round there three times this morning and there’s still no sign of him.’

‘He’s six foot tall, five foot wide, and looks like someone took a burning cheese grater to his face, how can you not find him? ’

‘Are you asking for another punch in the face? I’ve got a whole city to keep safe here, dayshift’s got better things to do than run around after your ungrateful arse!’ A clunk and the line went dead. The bastard had hung up on him.

Logan rammed the phone back into his pocket. ‘Typical. Ask them to do one simple thing and— Bloody hell!’ He grabbed the handle above the passenger door as Chalmers threw the car into the roundabout, tyres screeching all the way.

She ground her hands around the steering wheel. ‘They’re going to make a complaint, aren’t they? I don’t want that on my record, how am I supposed to make promotion with that hanging over my—’

‘Let them complain. The lab didn’t screw up on the fingerprints, they screwed up on the DNA. It’s not the victim’s: it’s the killer’s. So as soon as we get to the hospital. . .? ’

‘We get the killer.’ Chalmers brought her little pointy teeth out to shine. ‘One week on the job and I’ve solved a gangland execution.’

Logan stared at her. ‘You do know I’m sitting here, don’t you? ’

At least she had the decency to blush. ‘I meant, we’ve solved a gangland execution. Team effort. . . Sorry, Guv.’

‘Just drive.’

Footsteps clattered back from the spearmint-green walls. Paintings and arty photographs lined the corridor. People in dressing gowns shuffled to the side, leaning on the handrails, watching them march past.

Up the stairs.

Chalmers hurried on ahead, one of the uniformed officers seconded to Aberdeen Royal Infirmary clomping along behind her in full ninja black.

The other one hung back with Logan, puffing and panting as they climbed. ‘Could we . . . we no’ have . . . have taken the . . . bloody lift? ’

And let Gungho Gertrude get there first? No thanks.

They burst out onto the next floor.

Chalmers was staring at the ward signs hanging from the ceiling. She did a slow three-sixty, before shrugging her shoulders and poking the uniform in the shoulder. ‘Well? ’

‘Must be the next floor.’

Sod.
