They passed Lord’s Cricket Ground and continued up Wellington Road. Hepton had vague memories of a student party he had attended twenty years ago at a flat somewhere near Grove End Road. The hostess’ parents had bought the place for her. The night of the party, her friends had done their level best to wreck it. So much for peace and love.

Sanders turned left off Wellington Road and drove slowly down a narrower street of detached and semi-detached houses, some of them compact, others rising to three and four storeys. He stopped beside one of the smaller detached houses and flashed his lights once. A man appeared from nowhere and opened the garage attached to the side of the house. Sanders negotiated the car into the space and switched off the engine. Behind them, the garage doors were being pulled shut again, though the man operating them remained outside.

‘Home sweet home,’ Sanders said. ‘You lucky swine can get some rest now. I’ve still to write my report and meet with my bosses.’

The garage lights came on, and Hepton eased Jilly out of the back of the car. Sanders had opened another door, connecting with the house itself. Together they helped Jilly through it, along a carpeted hall and into a small, well-furnished living room, where she collapsed onto the sofa. Sanders pushed his hair back into place and straightened his tie.

‘Journalists,’ he said, staring at Jilly. ‘Right, I’d better be off. There are two bedrooms upstairs. Kitchen on the other side of the hall. Toilet next to the door to the garage, and bathroom upstairs. I think one of the bedrooms even has an en suite.’

‘All mod cons,’ said Hepton. ‘Is there a telephone?’

‘Yes, but I shouldn’t try using it. It just routes you straight through to a watcher team.’

‘Watcher?’

‘Surveillance.’

Hepton glanced around the room. ‘Bugged?’ he asked.

Sanders shrugged his shoulders. ‘Oh,’ he said, remembering something. ‘And if you need anything, either pick up the phone or tap on the kitchen window. There are a couple of security men front and back. Otherwise, sleep tight.’ He made to leave.

‘See you in the morning,’ said Hepton.
