'Because her scooter's not parked in the driveway.'

'Maybe she put it in the garage.'

'Her father's car is in the garage, she leaves the scooter in the driveway, if it matters to you…'

'You haven't been within a thousand miles of here before, you've never met this woman before… How come you know that sort of detail, or am I getting bullshit?'

'I had it checked.'

'You had it checked, down to whether she put a scooter into the garage or left it out in the driveway?'

'Checked.' Axel said it sharply, dismissive, like it was obvious that such a detail would be checked. The headquarters in Exeter of the Devon and Cornwall police, through their liaison officer, had provided information on the progress of an airmail letter through the city's sorting service, information on the hours worked by a young woman teacher, information on the nighttime parking of a scooter. He believed in detail. He thought that with detail people more easily stayed alive.

It had been the idea of Axel Moen. It was the operational plan of Axel Moen. What he wanted most, right now, was to smoke a cigarette. He opened the door beside him, felt the cool of the air, the grip of the sharp wind coming up off the pebble beach, heard the rustle of waves on stones. He reached back and grabbed for a windcheater. He stepped down onto the grass beside the road. Ahead of him, behind a low fence and a trimmed hedge, was the bungalow and the light was on over the door. He lit the cigarette, Lucky Strike, dragged on it, coughed and spat. He saw the shadowed bungalows and cottages, with their lights in the windows, stretching as a haphazard ribbon away up the lane to the bend round which the young woman would come on her scooter.

II It was the sort of place he knew. He wondered where the letter would be-in her room and on her bed or on her dressing table, on a stand in the hall, in the kitchen. He wondered whether she would tear the envelope open before she discarded her coat or her anorak, whether she would let it lie while she took herself to the bathroom for a wash or a pee. He heard Dwight Smythe open his door behind him, then slam it shut.
