Watch out, crime.

"Miss Marple. She's not going to frighten The Yardies is she? 'Leroy, give her the gun, she have a hat!'"


"Policemen asking questions are being policemen, but little old ladies asking questions are just being little old ladies."

Miss Marple, Miss Marple

There's a subgenre of Mystery Fiction called "Cozy Mysteries", a prevalent trope of which is the little old lady investigator. She is an older lady, usually retired, usually a Cool Old Lady, who has a knack for solving mysteries and who is always solving murders wherever she goes. She's usually an Amateur Sleuth, but occasionally she works for an agency or is a registered PI. The fact that people seem to keep dropping dead around her often makes her a Mystery Magnet. This sub-genre is also known as the "tea cozy mystery".

This trope makes a perverse sort of sense. Old women are supposed to be nosy, and attract little attention when they are. A grandmotherly type may be a lot better at prying relevant but embarrassing details from suspects than the gruff policeman. Finally, she is frequently protected by Even Evil Has Standards: who would dare to off the nice old lady?

More realistic takes on the concept have her solving minor misdemeanors and crimes which the police are too busy to solve. The most famous Little Old Lady Investigates character is probably Agatha Christie's Miss Marple.

Examples of Little Old Lady Investigates include:

Anime and Manga

  • Yattokame Tanteidan, a 2007 kids anime series about a young girl who solves mysteries with the help of her candy store owning grandmother and her grandmother's friends. As Japan has different social taboos on what kids' anime can contain, there are murders in this series.
  • Detective Conan has one episode where Kogoro is invited to a gathering of other famous detectives in the adult category as opposed to Shinichi's teen detective peers. Numbered among them is a little old lady detective who seems to have worked frequently with the two-fisted man of action private detective perhaps because their opposite strengths combine effectively. This ends up becoming a Subverted Trope since the little old lady uses her status as being Beneath Suspicion to murder her partner, and plan to do the same to everyone else.
  • Part of Saki's backstory in Hayate the Combat Butler is that her grandmother is the "legendary housemaid" Kijima Rei, who, among other things, has been known to solve mysteries and prevent assassinations.
  • An episode of the 1998 anime series Master Keaton, "A Case for Ladies", has the titular hero team up with an elderly English woman to solve a murder. The elderly woman displays quite a bit of genre savviness, as she unfavorably compares Keaton to Humphrey Bogart and Steve McQueen.

Comic Books

  • Madame Fatal is an old woman who fights crime and solves mysteries...sort of. Fatale is actually a man who took up the Madam Fatale disguise in order to find his long-lost daughter. Why he kept the disguise after he confirmed that his daughter was gone, we're not sure.
  • Finnish Donald Duck comic artist Kari Korhonen has put Grandma Duck in this role.
  • Prudence Petitpas was created by Maurice Maréchal in 1957 and got recently her own animated show.
  • The Many Murders of Miss Cranbourne (Rich Johnston, Simon Rohrmüller, Dark Horse Comics) parodies this sub-genre. The old lady happens to be a Holier Than Thou type, of antinomian variety. So as a self-assigned Hand Of God, she murders someone she doesn't approve and frames another, then steers a clueless policeman toward the latter. The police? They are too happy to have yet another case "solved" to be very suspicious about their luck.


  • The mystery movie spoof Murder By Death has many parodies of famous fictional sleuths. Miss Marple is parodied with Miss Jessica Marbles.
    • In a subversion, Miss Marbles isn't the wheelchair-bound old lady who first appears with a triumphant fanfare, but the merely middle-aged lady[1] pushing the wheelchair. The old lady is her former nurse.
  • Happens in the Korean film Omm-ah (Mom) about an elderly woman trying to clear her son of a murder charge.
  • Angela Lansbury played Miss Marple in the movie version of The Mirror Crack'd, long before Murder, She Wrote. This would make Jessica Fletcher some sort of Expy. (The Mirror Crack'd opened with a scene [not in the book], in which a mystery film was interrupted halfway through and Miss Marple deduced who the murderer must have been. The Pilot of Murder She Wrote opened with an identical scene.)
  • Mrs. Louisa Wilberforce of The Ladykillers discovered, more out of luck than detective work, that her band of musicians were actually criminals. Although indirectly, her actions put an end to them as thoroughly as Dirty Harry could have.


  • Agatha Christie's Miss Marple is the Trope Codifier. In one book she explains her success like this: "Policemen asking questions are being policemen, but little old ladies asking questions are just being little old ladies."
    • Dame Agatha's Tuppence Beresford of the Tommy and Tuppence books uses many aspects of the Little Old Lady Investigates, but isn't a pure version because she prefers to work on instinct, has a partner in her husband Tommy, and often works under the auspices of an official branch of the government. In N or M?, though, she essentially plays this straight while undercover as a doddering housewife and acting essentially as an independent agent.
  • Dorothy Gilman's Mrs. Pollifax is a little old lady investigative CIA agent. It's a bit more believable when you learn that she was originally hired by the CIA as a decoy courier by accident when her file was inadvertently placed in the "people we can use for this decoy run" stack instead of the "people we've reviewed and rejected" stack, but her Nosy Neighbor and Weirdness Magnet tendencies, combined with a very no-nonsense common-sense approach to whatever trouble she landed in[2], led her into more and more active assignments—this while still being essentially a part-timer who works for the CIA to keep her retirement years from being boring.
    • There's been two movies made featuring Mrs. Pollifax, the second was a made-for-TV movie in 1999 starring... you guessed it... Angela Lansbury.
    • Mrs. Pollifax isn't quite the normal little old lady either, as witnessed by the not more closely described "karate chop", which she delivers to many a foe, who is invariably rendered unconscious.
  • Dorothy Gilman also wrote a novel entitled The Clairvoyant Countess. The title character, Madame Marina Karitska is Russian and uh, clairvoyant. Her talent leads her into many investigations with a member of the police department Detective Lieutenant Pruden.
  • Gladys Mitchell's Mrs. Bradley (later Dame Beatrice Bradley). Justified Trope in that she was a psychoanalyst and had legitimate Home Office recognition.
  • Dave Stone parodied this trope in his 1997 Virgin New Adventures novel Ship of Fools with the character of Agatha Magpole. The inexplicably high rate of murders that occur when this little old lady is around turn out to be caused by her extremely powerful, yet subconscious, psychic abilities, which drive people to homicide.
  • Stuart Palmer's Hildegarde Withers, who also appeared in several movies in the 1930s.
  • Miss Climpson, the chatty, knitting, deeply religious old lady who works for Lord Peter Wimsey, gathering information in places he can't go without arousing suspicion!!
    • And yes, THIS is how the character talks and writes!
  • Terry Pratchett's Maskerade mixes this and Phantom of the Opera, parodying the heck out of both along the way.
  • Deconstructed brutally in the short story "Granny Gumption Solves a Murder" from 100 Dastardly Little Detective Stories. The titular Granny Gumption does indeed solve a murder, and confronts the murderer in his own home, without any witnesses—and mentions that she didn't tell anyone else that she figured out the truth. Needless to say, she becomes his next murder victim in an excruciatingly brutal death scene that starts with a broken jaw and Eye Scream and just gets worse from there.
    • You can read this vicious little story here if you like. (Note: link goes to PDF file.)
  • The No. 1 Ladies Detective Agency: Precious Ramotswe falls squarely into this category, despite the fact that she rarely solves murders, isn't all that old and is hardly little in the waist department.
    • The same goes for another of Alexander McCall Smith's heroines, Isabel Dalhousie of The Sunday Philosophy Club. Isabel is only in her forties, though, but is definitely nosy enough. One review has even described it in terms of tea and coziness.
  • The Miss Seeton series written by Hamilton Crane and Heron Carvic and I think one other H.C.[please verify] She is a retired art teacher and has an knack of drawing cartoons that see beneath the surface of character or event.
  • Patricia Wentworth wrote 32 novels featuring retired governess turned private investigator Miss Maud Silver.
  • Marion Mainwaring wrote a comic novel called Murder in Pastiche: or Nine Detectives All at Sea featuring pastiches of famous detectives. Miss Fan Sliver was an Expy of Miss Silver (with touches of Miss Marple) representing the whole school of Little Old Lady Investigates mysteries.
  • Simon Brett's Mrs. Pargeter is indeed a little old lady. On the other hand, she's the widow of a professional career criminal, and so has access to inside knowledge & contacts, which isn't so little-old-lady-like.
  • Ellen MacGregor's Miss Pickerell.

Live-Action TV

  • Jessica Fletcher (Angela Lansbury) in Murder, She Wrote is arguably the most famous TV variation.
  • In the Columbo episode "Murder by the Book," Jack Cassidy and Martin Milner portray the co-authors of the Mrs. Melville mysteries. Columbo creators Levinson and Link would later create Jessica Fletcher.
  • Hetty Wainthropp (Patricia "Hyacinth Bucket" Routledge) in Hetty Wainthropp Investigates is one of the more realistic takes on the trope, because she's a registered PI that by and large solves minor crimes and misdemeanors that the police can't be bothered with. She downright refuses to take murder cases.
    • Sometimes she is hired to investigate larger crimes with a clear bias, such as when a young girl keeps turning up at the scenes of arsons and her mother hires Hetty to find another suspect.
  • Mrs Bradley (Diana "Emma Peel" Rigg) in The Mrs. Bradley Mysteries. (Although the small and "bird-like" Mrs Bradley of the books is a better example.)
  • The Snoop Sisters, a 1970s-vintage series starring Helen Hayes and Mildred Natwick. With that surname, it was inevitable...
  • In the BBC children's series Marlene Marlowe Investigates, Marlene was assisted by her interfering Aunt Maud.
  • Rosemary & Thyme, though they are more middle-aged than elderly. One of them (Laura Thyme) is an ex-cop, the other (Rosemary Boxer) is an ex-biology professor, now they're professional gardeners and amateur sleuths.
