Murder City is a British crime drama series produced by Granada Television, first broadcast on 18 March 2004 on ITV, that focuses on two mismatched detectives, DI Susan Alembic (Amanda Donohoe) and DS Luke Stone (Kris Marshall), who scour London solving complex cases.

Whilst the premise of the show features a murder squad investigating complex cases in and around London, the drama created is centered around the realignment of character team-ups.

Although DI Susan Alembic (Amanda Donohoe) and DS Luke Stone (Kris Marshall) are the lead characters and partners, writer Robert Murphy frequently separates them at the beginning of each episode by providing them with individual cases to solve.

DI Susan Alembic is possibly one of the more talented DIs in her department, and she partners with the arguably less experienced Luke Stone.

DS Luke Stone is initially used to provide comic relief in the first series and is viewed as impetuous by Dumfries and Turner owing to his outrageous theories.

DC Alison Bain is a very keen, ambitious young detective who holds a passion for finding clues to fit the puzzle.

Often highlighted by Turner as a well-crafted sergeant of the future, Bain has worked her way up the ranks quickly and has found herself on the murder squad after just three years in the job.

In "Happy Families", he assists Turner in shifting partial financial responsibility for an out-of-control budget onto the DCI from a competing precinct.

In "Nothing Sacred", his character's ego was heavily featured, as it became clear that he cared less about listening to a suspect than attempting to win the 'case-solver' of the week prize offered by Turner.

Craven was initially designed to feature in a minor role, assisting Stone with the mathematical equations in "The Critical Path".

A star in Turner's eyes, as he was handpicked for the murder squad for an unblemished record as a serving officer, and from past recommendation from his former colleagues.

DCI Sebastian Turner is a very brash, say what you see style cop, who seems to have his mind set further on clean-up rates and budgets than actually caring whether he catches the killer or not.

However, after they hit it off after the first date, Stone finds himself becoming increasingly jealous, a fact which Annie is clearly aware of and plays upon to her advantage.
