He parked the Triumph, entered through the back door and went upstairs to the CIB office, a large, open-plan room with partitioned cubicles along the walls. His office was in one corner and overlooked the carpark. He happened to glance down and saw Ellen Destry park her car and enter the building. No sign of Scobie Sutton's car.
There were message slips on his desk. A Land Rover had been found. It bore dents and scratches on the passenger-side wing. The owner had reported it stolen at about the time Constable Tankard had found it while on patrol.
Challis stared at the phone. His hand reached out, collapsed on the desk again. He didn't want to call the prison and see how his wife was doing; he also ought not to use police time and resources. But a call from work would somehow make him feel less intimate and committed than a call from his home.
He made the call. His wife was back in her cell, on suicide watch. Did the inspector wish to talk to her? It might help her. No, Challis said. Tell her I called.
Then he went to the poky kitchen and brewed coffee, wondering who'd been at his packet of Lavazza. He'd learnt a long time ago always to provide his own tea and coffee. Police station coffee tended to come in a Maxwell House tin the size of a fuel drum and no one had ever heard of weak tea, let alone peppermint.
Finally, with a mug of coffee at his elbow, he opened the Progress, printed overnight and hot off the press. There was the Meddler's letter, and Tessa's column about the wanker with the ferret, and her sharper, more contentious observations about the asylum seekers and the detention centre. He could practically hear her spitting as she wrote that she'd found it necessary to point out to the worthy citizens of Waterloo that her objection to the local detention centre was not to that detention centre on that bit of land but to the notion of incarceration of asylum seekers in the first place.
No doubt she'd lose some advertising now, and the coppers of Waterloo police station would glance at him sideways and wonder about his relationship with the ratbag, leftist, pinko editor of the local rag.
He threw the newspaper into a bin and took out the Floater file. Not for the first time, he wondered about the thousands who go missing each year, unreported and apparently unloved and untraceable. Surely someone loved them? Surely someone remembered them? Here's a man prosperous enough to own a Rolex watch: surely he left a trace somewhere?
On an impulse, Challis reached for the local yellow pages and under the heading 'watchmakers' found a young woman who told him that the figures etched into the case of the Floater's Rolex were service marks. She jotted them down and said she'd make a few calls and let him know in a day or two who had serviced the watch.
So that was progress. Next Challis examined Kitty Casement's aerial photograph of the cannabis crop. There was a topographical map of the Peninsula on his wall but he was unable to match the tiny patch of coastline represented in the photograph to any part of the map.
A job for CIB and after that the Drug Squad, so he went in search of Ellen Destry. She was not in her cubicle. He walked downstairs and into a throng of uniformed and plain-clothes police, some cramming breakfast hamburgers from the fast-food joint across the street into their mouths.
Challis shuddered, saw Pam Murphy and edged toward her. 'What's going on?'
She blushed faintly, as if surprised that he knew her or would want to talk to her. In fact, Challis rated highly her detection abilities and knew she wanted to move on from uniformed work. 'The Monday talk, except it's on Tuesday this week.'
She pointed to a typed notice on the wall of the corridor. Challis read that Senior Sergeant Kellock would be addressing staff on 'Self-Selection and the Criminal Mind', starting at nine am, finishing at nine-forty. Kellock had scrawled at the bottom: 'All staff are urged to attend'.
Not for me, Challis thought, but then Ellen entered the corridor and tugged at his sleeve. 'Come on, Hal, you might learn something.'
He let her lead him into the main conference room and found himself leaning on the back wall with her, looking over a sea of heads to a table and a whiteboard at the front of the room.
'Scobie not here yet?'
Ellen shook her head. 'School run.'
Kellock was aptly named. It suggested a bullock, and the man was constructed of a thick pelt and a heavy superstructure of chest and shoulder bones and muscles. Waterloo was his station. He ran a tight ship. He also used to say that his door was always open, but last year someone had swiped the keys to the drugs safe and now the words were more metaphoric than literal.
'As you know,' he said, swinging his massive head about, 'I've been in the States and Europe on a Churchill Fellowship.'
'And pretty darned pleased with myself,' murmured Ellen in Challis's ear. Challis grinned.
'The topic of today's chat is a very useful finding made by criminologists in the UK,' Kellock said. 'I mean, it's so obvious and simple, all you can do is shake your head in wonder.'
He looked at them expectantly, waiting for them to bite, but the air in that little room was too warm, too stale, too overburdened with yawns and settling stomachs and aftershave and scented soaps and shampoos for that.
So he said, 'Simply put, your bad guy self-selects.'
He waited.
Nothing.
'What do I mean by that? Well, your criminal type tends not to let himself be bound by everyday laws and conventions. He'll park illegally, for example. He'll think nothing of speeding, running a red light, driving an unregistered and unroadworthy vehicle. And so on. There's a serial killer case in the States that was solved only because the killer was pulled over for driving with bald tyres. They opened the boot of his car and found his latest victim inside.'
Challis, like the others, looked at him attentively, wondering where this was going.
Frustration showing through for the first time, Kellock said, 'So, one of the best places to find a criminal is in the disabled-parking bay at your local supermarket.'
He referred to his notes. 'In a six months' study in Huddersfield in the north of England, it was found that one-third of illegal parkers had criminal records, half had committed previous road traffic offences, and a fifth were of immediate police interest owing to suspected connections with unsolved crimes.' His big head looked out at the room again. 'Those are significant figures, ladies and gentlemen. Furthermore, one in ten of the cars illegally parked by these characters was found to be unroadworthy and a fifth had a direct or indirect link to various criminal offences: getaway vehicle, transportation of stolen goods, etcetera, etcetera.'
The audience shifted, murmured. Ellen muttered to Challis, 'So what are we supposed to do, check out every disabled-parking spot?'
'So what I want you to do,' Kellock said, 'in the normal course of your duties, is run an immediate numberplate check on any car you see parked illegally. I want to test the Huddersfield study here on the Peninsula. If I'm not mistaken, the results will duplicate the Huddersfield results. Any questions?'
John Tankard was scowling. 'Sarge, why can't the traffic wardens do that? We've got enough on our plates as it is.'
'Because the traffic wardens don't have the power to arrest or the means to carry out computer searches of registration plates, that's why. Next question?'
There were a few desultory questions and someone shouted that no one ever said your average crim was a genius, and then the meeting broke up.
