Me and Guleed knew all this, of course, because not only had we asked for an IIP check before we’d arrived, and not only do I, as a matter of routine, keep dossiers on all the Rivers these days, but also because Beverley had got pissed a couple of weeks previously and spent all night bending my ear about Lady Ty and her ‘perfect bloody husband’. According to Bev there were only two things that could improve George McAllister-Thames in her mum’s eyes, one was a medical degree and the other was a bit more of a suntan.

‘And what do you do?’ asked Guleed.

‘Detective,’ said the lawyer, staring at her. ‘Really?’

‘I’m curious,’ said Guleed.

‘Hasn’t the starling told you?’ asked Lady Ty.

‘The starling?’

Lady Ty tilted her head in my direction.

‘Your colleague,’ she said.

‘She sits on a bunch of quangos,’ said Olivia, staring at a point on the table midway between us. ‘And is a director on like a gazillion boards.’

‘Five,’ said Lady Ty. ‘I’m a non-executive director for five firms.’

‘So not the Goddess of the River Tyburn then?’ asked Guleed.

I winced and Olivia rolled her eyes, but fortunately Lady Ty was in a whimsical mood.

‘That’s not precisely a job, now is it?’ she asked. ‘And rather beside the point.’

The lawyer opened his mouth to speak, but Guleed quickly turned to Olivia and asked how many people had been in the flat.

‘Don’t know,’ said Olivia.

‘I see,’ said Guleed. ‘Why don’t we start with the people you do know were there.’

Olivia squirmed in her seat like a five year old – this is why your brief tells you to keep your mouth shut during an interview. She made Guleed work for it, but in the end she confirmed that she along with several others had been in the flat. She hadn’t known the dead girl, Christina Chorley, and she didn’t know how the party had gained access to One Hyde Park.

‘We went through the hotel next door,’ she said. The Mandarin Oriental Hotel provided a complete package of services for the denizens of One Hyde Park, ranging from cleaning and catering to dog walking and aromatherapy, and there was an underground tunnel from the hotel to the estate. From there, the kids travelled up the segregated service core and into the flat.
