What attracted you to Why Women Kill?

For me, this was a wonderful opportunity to work with Marc Cherry, who I met a long time ago at the Emmys in all his glory. He sent me a wonderful letter saying that he always wanted to work with me. He explained how he had written the perfect role. I've always loved doing comedy. It's my favourite. Making people laugh is probably one of the most powerful things you can do, so Marc sent me the first script and I was pulled in immediately.

What else appealed to you about the project?

I also love the fact that this is a closed narrative. To me, that is very attractive because there's a beginning, a middle and an end. When I worked on Elementary for seven seasons, which was glorious, it was ongoing and we never knew what was going to happen next. It was more of a procedural, but this was different. I thought to myself, 'Wow! I get to relish in all of that colour and shoulder pads and glitter and hairspray - and I get to work with Jack Davenport.'

What do you think of your character in the show?

What I love about Simone is the fact that there's this over-indulgent lifestyle that she lives and she doesn't make any excuses for how she behaves. And yet, there's something very dramatic about how she's living her life. It's been a delight.
