DERVLA Kirwan has made a remarkable recovery since Christmas, when she exploded into a billion pieces (approximately) on the Doctor Who festive special.
Tonight she shows up for a guest appearance in episode two, playing a defence solicitor who’s about to give the CPS team a seriously hard time in the courtroom.
Why? How?
Well, because her hard-nosed character intends to put together one of the boldest defence cases you could imagine – one which, if she manages to pull it off, looks likely to turn the whole British legal system upside down.
On a more personal level, she also happens to be an old flame of James, so he’s not entirely unfamiliar with the way she operates.
