Caitlin's POV

I hadn't seen Milly and Millie for a while, so when they had a free weekend, they met me at the house I shared with Robyn.

They hadn't seen our marital home and were very impressed. Especially when they saw Robyn's Guinness certificates.

'That's so lovely' Milly told her, tears running down her cheeks as my wife told her the story of how she had achieved her records

Millie was looking at our DVD shelf and tears were running down her cheeks as she passed her fingers over the collection.

'You got some more' she said, wiping her tears.

'Yes, I did' I informed her. Millie replied she might check them out.

We said goodbye to Robyn and went to see Kate's new film that had just been released. I knew nothing about it, so I was very excited to see it.

It was a low budget film set mainly in a  police interview room. Kate was playing Louisa Gates one of the suspects. Her warehouse manager had been murdered and DI Smith and DS Weston were doing the interviews. My sister held her own against some really great actors. Eventually the warehouse manager's wife was found guilty of the crime

However in our post movie debrief in Burger King, Milly wasn't sure this was the right choice

'I don't know what it is' she said, 'But something doesn't add up'

Millie suggested she buy the DVD and maybe all will be revealed. We started to eat our meal
