‘They said it was a wake, sir.’

‘It was a fucking wake!’

‘Okay, I’m sorry. It seems you do things a little bit differently here than when we were in Manchester.’

‘We don’t do things differently,’ said Sparks, with an annoying calm. ‘Although we do thoroughly check our intelligence before we move in.’

‘What did you just say?’ said Erika.

‘I’m talking about last night.’

‘You’re sure about that?’

‘That’s enough!’ shouted Marsh, slamming his fist on the table.

Erika swallowed down her anger, and her hatred for Sparks. ‘Sir. My visit to The Crown had a purpose. It helped me secure new information about Andrea’s killer.’

Marsh sat down. ‘Go on,’ he said.

‘I now have a second witness who saw Andrea on the night she died in The Glue Pot, talking to a tall dark man and a blonde woman. This new witness went so far as to hint that Andrea could have been in a relationship with the man.’

‘Who is this new witness?’

‘Ivy Norris.’

Sparks rolled his eyes and looked at Marsh, ‘Do me a favour – Ivy Norris? Also goes by the names Jean McArdle, Beth Crosby, Paulette O’Brien?’

‘Sir, she—’

‘She’s a known time-waster,’ said Marsh.

‘But sir, I got the feeling she was scared when I pressed her about this man. It was genuine fear. I also believe, especially now we’ve found the phone packaging under Andrea’s bed, that Andrea had a second mobile phone, a phone she didn’t tell anyone about. I think she had friends that she didn’t want her fiancé, Giles Osborne, to know about . . .’

‘The records from Andrea’s old phone, the one she lost last year, came in last night,’ said Sparks.

‘No, I think Andrea had another phone. One she was still using. She bought a top-up voucher four months ago, we found it under her bed with the box,’ explained Erika.

‘It means nothing. It could’ve been for a friend,’ said Sparks. ‘Anyway, back to the records for the old phone that actually exist. I took the opportunity to go through them last night, and some interesting information has come to light.’

‘What’s that?’ asked Erika.

‘Several names come up in her call log, which I’ve cross-checked with Andrea’s Facebook messenger account. One of them is a bloke called Marco Frost . . . Ring any bells?’

Marsh looked at Erika.

‘Yes. He’s a barista who Andrea was, I dunno, dating a while back. An Italian guy, works at a coffee place in Soho?’

Sparks nodded and went on, ‘He made hundreds of calls to Andrea’s old phone. The calls were over a period of ten months, between May 2013 and March 2014.’

‘Why wasn’t I told that the phone records had come through?’ demanded Erika.

‘It was late last night. I thought you might have wanted to get your beauty sleep,’ said Sparks.

‘Sparks, get on with it,’ said Marsh.

‘Okay. So I went back through the interview I did with the Douglas-Browns, when Andrea had first gone missing. And they mentioned this Marco Frost. Andrea did date him briefly for a month at the beginning of 2013. Then she ditched him, and the phone calls started. He turned up at the house several times. Wouldn’t take no for an answer. Sir Simon actually had a police officer visit Marco Frost and speak to him about his unhealthy interest in Andrea.’

‘Why wasn’t this mentioned to me before?’ asked Erika.

‘My notes were available in the file.’

‘I never got them.’

‘Well, they were available.’

‘All right, all right, all right. Let’s act like adults,’ said Marsh, impatiently. ‘Go on, DCI Sparks.’

‘Okay. So I went back to Andrea’s new phone, where, as we know, there’s not much to go on. She checked her emails on that phone too, and there was a load of e-invites to parties and events—’

‘Yes, the team has been through them, there are hundreds. She had memberships with lots of private clubs,’ said Erika.

Sparks continued, ‘There was an e-invite for an event at the Rivoli Ballroom on Thursday 8th January, the night she vanished. It was a fancy burlesque show organised by one of the clubs where she was a member.’

‘Yes, and on that same night Andrea had invites to several other parties in London. As I say, she was on loads of mailing lists . . . And she had already arranged to meet her brother and sister at the cinema.’
