Fiona Shaw's stunning character Carolyn Martens in 'Killing Eve' makes us forget all about the vile Aunt Petunia

Shaw reprises her role as the crisp and efficient MI6 secret agent Carolyn Martens, who is pretty much at the root of Eve and Villanelle's obsession

This article contains spoilers for Killing Eve season 2.

One of the earliest memories of the brilliant Fiona Shaw has got to be watching her as the unpleasant, curt Aunt Petunia in the 'Harry' Potter films. We grew up despising the Durselys, especially Shaw's character Petunia, purely because of how vile and vain she was when it came to Harry.

But gone are those days, and Shaw isn't the mean old lady playing the rude aunt anymore. These days she is better known as one exceptionally skilled MI6 agent, Carolyn Martens on BBC America's 'Killing Eve', and people can't have enough of it.
