‘I take it that’s the good-looking man who wears the polo shirts with a crocodile on them?’ Jane asked.

Rachel had a twinkle in her eyes as she smiled, and nodded her head repeatedly with a childlike innocence.

Emma looked at Teflon. ‘She likes him . . . a lot.’

Rachel frowned at her sister and handed Jane the sketchbook.

Jane opened her shoulder bag and took out the Exchange & Mart paper Kingston had given her. As Jane spoke Emma signed to her sister.

‘I’d like you to go through the cars for sale section with my colleague Lloyd and see if you can identify the car the man in the camel hair coat was driving.’

Rachel nodded and signed to Emma.

‘She said she can try and draw it if you want.’

‘Look through the magazine first, then if you don’t see the car do the drawing. Meanwhile I’ll help Emma make a nice cup of tea for us all.’

‘Can I have a coffee with milk and sugar please?’ Teflon asked.

Jane followed Emma to the kitchen.

‘Is something wrong, Jane?’ a worried-looking Emma asked.

‘What makes you think that?’

‘You didn’t say anything about your investigation to Rachel and seemed eager to be alone with me.’

Jane realised Emma was more perceptive than she thought.

‘Actually, there is something I need to speak to you in private about.’

‘Do those men know it was Rachel who told you about them?’ she asked, with a genuine look of concern.

Jane shook her head emphatically. ‘We haven’t spoken to them and only my team know about you and Rachel.’

‘Was it them that committed the robbery and shot the police officers?’

‘We don’t know for certain, and even with what Rachel told us we haven’t enough to arrest them – so there’s nothing for you to worry about.’

‘That’s a relief. Can I tell Rachel?’

‘Of course. What I want to speak to you about concerns yours and Rachel’s childhood.’

‘There’s not much to tell, really. As you know, our parents died in a car crash and we were raised in a children’s home.’

‘Was it St Cuthbert’s in Tottenham?’

‘Yes, why do you ask?’

‘A colleague of mine spoke to a nun at St Cuthbert’s. She told him about twin girls called Emira and Rasheda Osman, who were sent there in 1958 after a car crash.’

‘I’ve never heard those names before.’ Emma looked away nervously.

‘The nun said one girl was deaf and the other had a deformed left hand as a result of the crash. To me, there can be no doubt she was talking about you and Rachel.’
