‘Er … yes, she mentioned her once or twice.’

Steph thought of the business card with the name Camilla and a phone number. ‘I think I might know who she is. That’s not exactly true, actually. I think I’ve found a number for her. I can’t explain now, but I’m going to phone her.’

‘So you’re not giving up on me just yet?’ There was genuine hope in Sonia’s voice.

‘No, I’m not giving up on either you or Elizabeth,’ reassured Steph. She stood up and began walking back along the grass path through the roses. ‘I’ll call you again when there’s something to report.’

‘Thank you, Steph. Thank you so much.’

‘Let’s not get our hopes up too much.’

‘I know you won’t let us down.’

Ending the call, Steph slipped her hand into her pocket and took out the card she’d found in Elizabeth’s coat. In her haste to put the coat back in the wardrobe before Pru caught her, she had stuffed the card into her own pocket. It couldn’t be a coincidence, not with a name like Camilla. Surely there was a connection. At last she had a lead to follow, one that wasn’t a member of the Sinclair family.

She stopped before she reached the edge of the Rose Garden and, using her phone, took a picture of the card which she then emailed to herself as back-up. The card had taken on a new significance and the last thing she wanted to do now was to lose it.

She thought back to her chat with Cameron. The name in the notebook wasn’t his name, so could it be Camilla? She flipped through the pages and looked closely at the comment ‘Cam … 230’. She let out a deflated sigh. It definitely didn’t say Camilla. She studied the writing, which was unusually squiggly, as if written in a hurry. And then it dawned on her. It said neither Cameron nor Camilla.

‘Camera!’ said Steph, out loud. ‘It says camera.’ The end squiggle was a dash leading towards the numbers. Perhaps it wasn’t significant at all, but the way it was circled, Steph couldn’t help feeling she was missing something. She looked at the rest of the list. Immediately below was a phone number, which had been underlined in the same red pen, and then 2206 on the same line, written in the same pen. Again, it seemed important and Steph was sure it was connected in some way.

Steph Googled the phone number. The results shouldn’t have been surprising, she thought as she looked at the screen on her phone. The landline number belonged to a company called Jaspers, who were an online audio and visual equipment supplier, specialising in CCTV and monitoring.
