Characterisation Nicknamed the "female sleuth" by the
Daily Record, and Nancy Banks-Smith from
The Guardian characterised her as "strict". Naomi Mcelroy described Marsden as a "curly-haired copper", but said as a detective she was "rubbish"; Polly Hudson from
The Daily Mirror similarly opined, saying she was "useless" (as did Mcelroy), and stated that Marsden was "making a right pig's ear" of investigating Archie's (Lamb) murder. The
Daily Mirror Tony Stewart characterised her as "vindictive".
Introduction, 2002 and 2003 returns Marsden first appeared on 5 March 2001 in the "Who Shot Phil?" storyline. A source in the
Daily Record said, "Sooner or later the truth will out. But until then there's going to be a lot of probing going on." She left on 27 March 2001 after unsuccessfully identifying the shooter (who turned out to be Lisa). In 2002 she appeared in January, April and from 14 November to 6 December. In November, when Marsden returns, the police suspect that Phil has murdered his ex-wife Lisa.
The Daily Mirror said, "They are the words Phil Mitchell has heard many times before. 'You're nicked', baldy. Intrepid DCI Marsden may not be a
Jane Tennison, but she's nabbed her prime suspect. "I've got some good news for you, Phil," she says, after arresting him on suspicion of murder. "The police in Portugal found your jacket. Unfortunately for you, it's covered in blood. Mrs Fowler's blood..." In 2003, Marsden returned in March July, August, November and for a longer stint in December.
Who Killed Archie? and 2012 returns (

Digital Spy forum members had previously pointed out that her return was hinted at in a photo on the official
EastEnders website and in a feature ("Script Peek") where Phil is quoted as saying, "I know exactly what makes her tick" before adding "I've wriggled off her hook so many times. She's already picturing me standing in the dock" in the 29 December episode....I really thought Marsden was no more. It was a really great surprise because I’d just finished a year’s run at the
National Theatre, appearing in a new play called
England People Very Nice – so it couldn’t have come at a better time." Although Stanton did not know who murdered Archie, she guessed that it could be Stacey Slater (which turned out to be correct). Speaking of this, she said that Sophie was one of the few to correctly guess it was Stacey. "I had an epiphany about a week before the live episode. It was a memory of the whole Who Shot Phil? storyline, and how there were eight different suspects, including some really hard blokes, and it turned out to be Lisa. I knew DCI Marsden wasn’t going to get the culprit, because of a couple of scenes of the following episode we’d shot in December, and I thought that narratively, Stacey was the only person who the audience would forgive, and who could get away with it. That was my theory and it turned out to be right!" Marsden left on 22 February 2010, and returned on 5 January 2012. She returned after Phil is
framed for
Kevin Wicks' (
Phil Daniels)'s death and that of a homeless man, who died accidentally in a car-lot fire (part of an insurance scam).
Digital Spy reported that Marsden re-opens the investigation into Stella's death, "suspecting that all is not what it seems". Finally, Marsden returned for two single episodes on 17 August 2012. Whilst viewers know
Bobby Beale (Eliot Carrington) is the culprit, Marsden,
Samantha Keeble (
Alison Newman) and
Cameron Bryant (
Glen Wallace) will reportedly make an arrest for the murder, arresting an innocent suspect. ==Storylines==
