Who Killed The Body In The Library In Marple?

The killer in 'The Body in the Library' is Raymond Starr, Ruby Keene’s dance partner. He’s the kind of villain who hides behind a smile, pretending to help the investigation while secretly panicking. The murder is part of a botched blackmail plot, and his mistake was thinking a small-town sleuth like Miss Marple wouldn’t notice his slip-ups. The way he moves the body to the library to create confusion is clever but ultimately his undoing. Christie nails the irony—his 'artistic' temperament (he’s a dancer) makes him overly meticulous, leaving traces Miss Marple spots instantly. His arrest scene is *chef’s kiss*—all charm crumbling into desperation.

I just finished rewatching 'The Body in the Library' from 'Miss Marple,' and the killer reveal still gives me chills! The victim is Ruby Keene, a young dancer, and the murderer is actually her dance partner, Raymond Starr. It's one of those Agatha Christie twists where the seemingly charming guy turns out to be the worst. The way he orchestrates the whole thing—using Josie Turner as a decoy body to confuse everyone—is downright sinister. The motive? Cold, hard cash. He was in on a scheme with Ruby to blackmail a wealthy old man, but greed got the better of him. Miss Marple pieces it all together with her signature sharp eye for human nature, noticing how Raymond's 'perfect alibi' was too perfect. The final confrontation is so satisfying because you realize all the tiny clues were there, like his weirdly specific knowledge of the crime scene.

What makes this case stand out is how it plays with expectations. The library setting feels so proper and civilized, but the crime itself is messy and brutal. Raymond’s downfall comes from underestimating Miss Marple—he thinks he’s outsmarted everyone, but her quiet observation of his nervous habits (like fiddling with his tie) seals his fate. It’s a classic case of 'the butler didn’t do it' but the guy you least suspect because he’s too busy playing the hero.

One aspect I rarely see discussed is the social commentary. The killer, Basil Blake, is from a somewhat nouveau riche, less stable class. He invades the space of the established gentry (the library) with his sordid crime. Miss Marple, representing the sharp-eyed, traditional middle class, solves the crime and restores order. The Bantrys, the landed gentry, are helpless without her. Christie is making a subtle point about where real intelligence and moral authority reside in a changing England. It's not with the flashy newcomers or the complacent aristocracy, but with the observant, experienced middle. So Basil isn't just a murderer; he's a symbol of disruptive, amoral modernity that must be expelled. The solution is a societal correction as much as a criminal one.

Can we appreciate Colonel Bantry's reaction? He's just baffled. His library, his sanctuary, violated. It's the perfect way to draw the reader in. We're outraged on his behalf. That emotional hook makes us invested before we even care about Ruby Keene. The killer, Basil Blake, counted on that outrage clouding the investigation. He wanted the police to focus on the Bantrys' enemies, not his own. It's a clever bit of psychological manipulation. Miss Marple is immune to it because she isn't shocked by human frailty. She expects to find passion and violence anywhere, even in a library. So while Blake successfully manipulates the police and the public with his shocking choice of location, he fails to manipulate the one person who sees the crime not as a violation of space, but as an expression of human failing.
