● Grace is such a lovely place to go to work that the days kind of all meld into one. Luckily, we do one episode at a time. If we did the three of them together I would be in real trouble, which we did with Life On Mars. We used to crossover the episodes. We had no idea what we were talking about or where we were.

● With Craig and Laura [DS Norman Potting and DS Bella Moy] together it's murder to keep a straight face sometimes! It's very hard to concentrate but it's fun. We always get it done in the end. It's good because it lightens the mood. This is heavy stuff. You need that release, otherwise it would be a very depressing day at work.
