‘Has he been unwell, or acting out of character at all, Mrs Swan?’ Salter asked, sipping the coffee that had appeared courtesy of an adult daughter who was comforting her mother.
‘No. My husband was a creature of habit. He came and went at certain times. Had clothes for work and clothes for the weekend. He always told me if something was bothering him. And I could tell, you know. It’s like that once you’ve been married long enough. But to leave his wallet and phone in a public place? He’d never be so careless.’ The daughter handed her mother more tissues from the box rapidly being used up and Callanach checked his watch. The library wasn’t normally open until later but the caretaker had agreed to meet them there and open up. If Michael Swan had left a note anywhere, it was likely to be on his desk.
At the library it was confirmed that Michael Swan had checked out with his swipe card at 8.37 p.m. the previous day. Salter immediately radioed through to the station for a CCTV check of the route he’d have taken to the point where his wallet and mobile had been abandoned. Callanach moved forward at the caretaker’s beckoning and looked through the documents left on a modern reception desk.
‘Is this where Mr Swan would have spent most of his time?’ Callanach asked.
‘Aye, here to check books in and out. The building is on two levels. Library down here, meeting rooms upstairs, used for educational programmes and whatnot. Sometimes authors come here to talk about their books. Other evenings it’s used for community meetings, you know, the local historical society, a dieting club,’ the caretaker leaned down to whisper in Callanach’s ear, ‘and the local alcohol and drug addiction service is in on a Wednesday, but we’re not supposed to talk about that. Bit sensitive for those attending, you know.’
‘And this is everything? He has no employee locker, no personal area?’ Callanach asked.
‘There’s a little staff area behind that glass there. Used for administration, but also for coats, mugs, a place to concentrate without being pestered.’
The caretaker unlocked another door into a thin room at the side of the main library hall, half wall and half obscured glass, with desks lining one side, and full of the sort of mess that busy, hard-working people leave in their wake.
‘Here you go, laddie. This was Mr Swan’s mug. I’m sure it’s all just a terrible mistake. He’s a good man. No harm’ll have come.’ The caretaker picked up a well-used, slightly chipped mug bearing the legend, ‘Eat well, drink well, read well’, clutching it to his chest rather too tightly.
‘Thank you,’ Callanach said. ‘We’ll have a quick look round and let you get on with your day.’ Across the main hall of books was the entrance hall where they’d come in. Steps leading upwards were signposted to education rooms. Another side door bore no marker. ‘What’s through there?’ Callanach asked the caretaker.
‘That goes down into the basement. Holds books not currently on the shelves, ones that need mending or replacing, old posters, redundant furniture. More of a storeroom than anything.’
‘Did Mr Swan have a key to that as well as to the front door?’ Callanach asked.
‘Not on his own set, although there’s one kept on the keys in the desk so the staff can get in if someone asks for a book that’s not on display.’
‘Could you get it for me please?’ Callanach asked.
‘I’m not sure why he’d have left anything in there, particularly. But I’ll open up anyway.’
The caretaker walked ahead and Callanach followed, checking the time. He was due in a meeting with the press liaison officer to give another useless update on the Sim Thorburn case, but he should at least phone and say he’d be delayed. The heavy door swung open and the caretaker reached around the side to flip on the lights. Nothing happened.
‘Fuse box?’ Callanach asked.
‘I’ll go and see,’ the caretaker said. ‘Give me a moment.’ He wandered off back into the main hall as Callanach stepped inside, taking the few steps down into the basement. The door had been heavier than he’d anticipated and it swung shut behind him. The area was effectively windowless, with a dim pane of glass glowing green-brown with moss and mud from decades of a lack of cleaning, and only the faintest vein of light from beneath the door at the top of the steps. Something rotten hung in the air, as if the basement had been built too close to a sewer pipe, polluting with its sulphurous putrescence.
Callanach took out his mobile and switched on the torch app that would drain the battery in no time, but it would do for him to get his bearings and stop wasting any more minutes. He walked between rows of books, all neatly stored, with boxes at the end of each line containing the expected jumble and junk. Children’s toys, some costumes, ageing furniture that no one had decided what to do with. He turned a corner, letting his phone shine at the floor, sensing rather than seeing obstacles as he walked away from the neat rows of books. There was a noise behind him. He spun round, disoriented. One foot flew out from beneath him and he threw a hand to the side to grab what he could to stabilise himself. His other foot followed the same fate, slipping on the floor, and his free arm shot up rather than out, clutching at the first thing it touched. It was a textile, smooth and slippery, wet on one side. Callanach shouted as he fell, landing on his back as whatever his hand had found loosened in his grasp. He closed his eyes as pain shot through his coccyx. A few moments later he repositioned his mobile and shone the light upwards.
Above him was, without a doubt, the body of Michael Swan. He had been suspended horizontally from a metal structural beam by his neck and his bound ankles. Callanach could only see fragments as the beam of torchlight moved, shakily, along the length of the corpse. Whoever had hung him had almost entirely skinned Swan’s face. Callanach had read numerous articles about it but never seen a case where it had been done. An incision had been made around the outer circle of facial skin, starting at one side of the lower jaw, heading up around the cheekbone, across the forehead and back down the other side. Finally, like a perfectly skinned rabbit, his face had been peeled.
Callanach felt the stickiness in his palm and knew that the resulting flap of skin had been what he’d grabbed as he’d slipped. He didn’t need the torchlight to confirm the pool of blood he was lying in.
‘Police officer, put down your weapons,’ Salter shouted from the doorway, no doubt assuming an assault and possible injury.
‘I’m all right, Salter. There’s no one else here.’ He may not have checked every inch of it, but Callanach was sure the assailant had left the building the night before, taking Swan’s mobile and wallet with them.
‘The fuse box is fine, the light bulbs must all have blown.’ Callanach could hear the caretaker’s voice getting closer.
‘Salter, get everyone else out of here right now. Close down the scene. Contact the pathologist immediately and call forensics in. Do not enter. I’ve already compromised the evidence.’
He could hear urgent instructions being given and the sound of footsteps disappearing away.
‘You sure you’re not hurt, sir? It sounded bad,’ Salter called.
Callanach unlaced his boots and left them where he’d trodden so as not to spread any more evidence around the room.
‘Missing person confirmed deceased. I’m uninjured. It’s going to be a difficult crime scene to process. I want an absolute lockdown on communications going out of here.’ Callanach moved gingerly towards the door, feeling his lower back as he went. He’d cracked it hard as he went down and parts of his legs were numb.
‘What the fuck?’ Salter said before she could stop herself. She started forwards to grab him, but Callanach raised a warning hand.
‘Don’t touch me,’ he said. ‘If there were trace fibres or evidence on the floor, they’re on me now.’
‘God, sir, you’re
