The Ace of Spades

The Ace of Spades is a crowded underground den in Chelsea where a cryptic newspaper advertisement leads Tommy Beresford and Tuppence Beresford from a fashionable evening’s entertainment into the discovery of a stabbing. Its contrast between theatrical fancy dress and concealed danger makes the restaurant more than a destination: the screened booths that promise privacy also provide the setting for a crime hidden in plain sight.

Identity and Setting

Tuppence describes the Ace of Spades as a queer underground den, a place she had heard was fashionable during large costume events. Visitors came there for bacon and eggs and Welsh rabbits, and booths screened off around the walls offered couples a measure of seclusion. Tommy’s first response is to treat the proposed visit as an expensive way to learn bridge; Tuppence rejects that interpretation, recognizing the name as part of a coded advertisement.

The restaurant’s appearance is mean and tawdry rather than glamorous. Yet on the night Tommy and Tuppence visit, it is crowded with couples in fancy dress, carrying the revelry of the Three Arts Ball into a markedly less respectable setting. That collision of spectacle and shabbiness gives the place its distinctive atmosphere: costumes and masks furnish a public performance, while the closed booths divide the room into private spaces.

The Advertisement and the Visit

The advertisement reads, “I should go three hearts. 12 tricks. Ace of Spades. Necessary to finesse the King.” Tuppence interprets “three hearts” as the Three Arts Ball, “12 tricks” as twelve o’clock, and the Ace of Spades as the restaurant itself. The final instruction, about finessing the King, remains unexplained; she proposes that they go and discover what it means. The restaurant thus enters the investigation not through ordinary directions but through a message whose playful bridge vocabulary conceals a practical lead.

At ten minutes to twelve, Tommy and Tuppence drive from the ball to the Ace of Spades. They secure one of the booths and deliberately leave its doors slightly ajar, allowing them to watch what is happening beyond their enclosure. Their arrangement makes the booth both cover and lookout: they can remain among the costumed couples while scanning the room for the people connected with the clue. Tuppence wonders which guests are “our people,” and the pair speculate about figures in costume, including a Columbine with a red Mephistopheles and a supposed wicked Mandarin beside a woman dressed as a Battleship.

The Murder Discovery

The restaurant’s curtained-off arrangement becomes consequential when Tuppence senses that something is wrong and leaves their booth despite Tommy following her. The adjoining booth’s doors are closed. Tuppence pushes them apart and enters, with Tommy immediately behind her. Inside, a young woman dressed as the Queen of Hearts sits hunched against the wall, watching them steadily through her mask but making no movement.

The costume’s red-and-white design has been violently disrupted: on the left side, there is more red than the pattern should contain. Tommy sees the hilt of a jewelled dagger just below the woman’s heart. Tuppence drops to her knees beside her and recognizes that she is still alive; she urgently tells Tommy to seize the manager and have a doctor summoned at once. The scene turns the restaurant’s masked festivities into an emergency, and the secluded booth that had served as a vantage point becomes the threshold to a life-threatening attack.

Narrative Significance

The Ace of Spades links the story’s coded language to a concrete place and then to an abrupt physical danger. The advertisement’s sequence of bridge terms supplies the route and the hour, but its last instruction is not resolved before the visit becomes urgent. At the restaurant, the same details that make observation possible—the crowd, costumes, masks, and screened booths—also conceal what has happened in the adjoining enclosure.

The location’s name first appears as a puzzle element, then as the destination Tuppence identifies, and finally as the room in which she and Tommy encounter the wounded Queen of Hearts. That movement from wordplay to investigation to violence gives the Ace of Spades a structural role in the episode: it is where a seemingly playful message acquires immediate human stakes.
