Karrin Murphy

A former member of the Chicago Police Department's Special Investigations division, Karrin Murphy is a human female. She first appears in Storm Front.

Description
Karrin Murphy is the oldest child of Marion and Collin Murphy. She has at least two brothers and one sister, Lisa. She is short-statured, blonde and blue-eyed. (ref)

Collin Murphy was a senior detective in the Chicago PD and an investigator in the Black Cat Department, covering the same territory as the modern-day S.I. department. When Karrin was 11, he committed suicide.

Murphy's place is in the neighborhood of Bucktown in Chicago. It's a small house left to her by her grandmother.

Karrin is a nominal Catholic, as is her family, (ref Blood Rites). Her father's nickname for her was "Karrie", and the only other person to call her that is Henry Rawlins, who was once saved from a demon by Collin Murphy who came bearing a shotgun loaded with rock salt.

Since Harry died, she has become far more paranoid, granted it is justified. Murphy is listed as executor on Harry's bank lock box, and he entrusts her with seeing to the care of his daughter.

She's one of the few privy to the following secrets about Harry: Thomas Raith is Harry's brother. Margaret Angelica is Harry's daughter. She also knows that Harry suspects the existence of a Black Council.

Summer Knight
In Summer Knight, it comes out that when she was seventeen years old, she married Gregory Taggart, who Harry Dresden estimates to be about a decade older. Some time later Taggart left her. They tried to reconcile a few times, but it always ended in fighting.

Her ex-husband Gregory Taggart died, 43 years old, at night, after a long fight against cancer. He had not told Murphy about his illness, and she was devastated when learning of his death by discovering his obituary in the Tribune newspaper. She regretted not having been able to say good-bye.

Blood Rites
In Blood Rites, Karrin reveals that she had been married to Rich at some point, but were divorced. He felt she was ignoring him for her job; she thought he wanted her to stay at home so she wouldn't make him look bad at work and was using the excuse of wanting to have kids as a rationalization. Murphy flips when she finds out that Rich is engaged to marry her kid sister, Lisa Murphy. Rich is a police detective in New Orleans and is getting transferred to the Chicago FBI to be near Lisa and her family.

Proven Guilty
In Proven Guilty, Rich (now called Rick) is an FBI agent called in to assist the Homicide Department in the SplatterCon!!! case by Detective Greene and aids him in questioning Molly. Karrin intercedes. She does not get along with her ex-husband.

Dead Beat
In Dead Beat, Karrin went on a sexually-loaded vacation to Hawaii with Jared Kincaid,making Harry quite jealous. Ironically, though Karrin doesn't appear in the book, all of Harry's actions are manipulated by his desire to protect her from blackmail.

Small Favor
In Small Favor, Karrin is very distraught over how badly wounded Kincaid is after engaging the Denarians at the Shedd Aquarium. Later, she says it hurt to see him that way, but she is not sure how involved she is. She thinks it's stupid to get hung up on him since he's not interested in getting serious. Harry believes it's that Karrin's detachment from Kincaid that keeps her able to be close to him. At the end, Karrin has an odd look on her face as she watched Kincaid, wounded but looking rather paternal, crawl in next to the wounded Ivy, with his Glock.

Her relationship with Kincaid is disrupted by her burgeoning romantic feelings towards Dresden.

Proven Guilty
In Proven Guilty, she admits to being attracted to Harry, but is unwilling to act on it. First, she doesn't want to ruin their friendship and working relationship. Second, she worries about their difference in lifespans: as a wizard, Harry will live for centuries, and she wants someone who can grow old with her and raise a family.

Small Favor
In Small Favor, Karrin tells Harry that she does not think Anastasia Luccio is right for him.

Work life
Whenever something inexplicable happens that the Chicago PD must handle, they send it over to Special Investigations. Conveniently, this is also where they tend to transfer out-of-favor officers.

She uses Harry Dresden as a walking supernatural library, hiring him as a police consultant.

Proven Guilty
At the end of Proven Guilty, Karrin Murphy is demoted to the rank of Detective Sergeant, after leaving the scene of the crime for 24 hours while she was on duty.

She held a blazing sword in her hand and she shone so bright and beautiful and terrifying in her anger that it was hard to see. The Sight, I realized, dimly. I was seeing her for who she was."

Blood Rites
When Harry Sees her again in Blood Rites she appears as an angel, her eyes were "azure flame", she bore a fiery shaft in her hands. Her robes had become smudged with filth, blood, and smoke. She bled from several wounds and moved like she was in terrible pain.

Rudolph meddled in that.

White Night
In White Night, Murphy calls Dresden in on a murder case, she's a sergeant now and says she'll pay him herself. The victim was a practitioner whose death appears to be a suicide.

In the end of White Night, Harry reached into Murphy's bag to get his .44 gun and he saw a "boxy little machine gun". Murphy said its a P90 and that the magazine has clear plastic so you can always see how many rounds you have left. She got it in a box of Belgium chocolates from Jared Kincaid the year before. The P90 made it's first appearance in the battle of the Deeps.

She was with Thomas on his boat when they pulled Harry out of the water off the island of Demonreach (as yet unnamed). When Deirdre attacked Harry as he tried to get into the boat, she pulled her P-90 on the Denarian, but it was knocked out of her hands. Harry offered her Fidelacchius and when she draws it, it lights up blinding Deirdre, who disappeared under the water, allowing them to escape.
