Full Story Summary: The Triple Murder at the Grand Alpine
Spoiler warning: This summary recounts the entire plot, including the ending.
In 1950, Jane Marple arrives at the Grand Alpine Hotel above St. Celeste with her friend Mrs. Bantry and their companion Diana Glass.
The opulent, snow‑draped resort buzzes with elegant guests, among them the charismatic politician Anthony Narracott, his quiet wife Catherine, and Hollywood star Sylvia Sinclair.
Trouble surfaces quickly. A jar of rat poison is found in the Narracotts’ room, and Anthony, who has a severe nut allergy, almost dies after eating a dessert laced with nuts.
A shabby man named Bruno Crane also checks in, claiming to be Anthony’s wartime brother‑in‑arms. Their reunion is tense and transactional.
On a cold morning, the first gondola arrives at the summit carrying Anthony Narracott’s body. He has been poisoned via his coffee flask, tampered with while he answered a fake telephone call at reception.
Panic erupts when Bruno Crane commandeers the cog railway train. Diana Glass runs after him, and the ensuing struggle causes a crash that blocks the tunnel, leaving the hotel completely cut off.
A guest who introduces himself as Inspector Moreau of the Paris Judiciaire takes charge of the investigation and enlists Miss Marple’s help. But the killings do not stop.
Bruno Crane receives a note promising him his “due” from a hidden cache of gold; he follows the instructions to a remote copse of trees and is bludgeoned to death. Soon after, Moreau himself is found dead on the snow below a balcony.
Miss Marple untangles the true history. During the war, Anthony Narracott and Bruno Crane murdered a group of French Resistance fighters—the Wolves of the Mountain—and stole a Nazi gold shipment they were supposed to destroy.
Narracott used the fake heroism to build a political career and returned to the Grand Alpine to retrieve the gold. Diana Glass is revealed as the sole surviving Resistance member, driven by vengeance. The fake inspector is Kristoph Mauer, a Swiss banker also hunting the treasure.
The real shock comes when Miss Marple exposes the two women who seemed to be rivals for Anthony’s affection.
Catherine Narracott and Sylvia Sinclair were actually secret allies. Both had suffered Anthony’s cruelty. Together they planned his murder and the elimination of anyone who stood between them and the Nazi gold.
They used elaborate disguises—dressing as nuns, deploying a massive Irish wolfhound to distract witnesses—and created watertight alibis for each of the three killings.
As the weather clears, Catherine and Sylvia flee over the treacherous mountain pass toward Italy, dragging the gold behind them. Diana intercepts them but is shot and left for dead as an avalanche descends.
A gondola attendant rescues her. Miss Marple, anticipating the killers’ escape route to Istanbul, alerts the authorities.
Italian police arrest Catherine Narracott and Sylvia Sinclair aboard the Orient Express in Venice. Later, in St. Mary Mead, Miss Marple quietly reflects on the enduring “stain” of wickedness, while Diana Glass moves toward a new life at the Foreign Office.
The story weaves several dark threads together: the betrayal of wartime allies, the corrosion of greed, the way individuals reconstruct their identities, and the dangerous alliance of two women pushed beyond endurance.
Every major crime in the novel springs from a single, long‑buried act of treachery.
