Death of a Child: The victim in this story is twelve or thirteen years old.

Every single person Poirot talks to dismisses the possibility that she might've actually witnessed a murder as she claimed completely out of hand.

Compulsive Liar: Joyce Reynolds' only notable character trait.

He is killed for it, true to Agatha Christie form.

Blackmail Backfire: Joyce's brother Leopold blackmails Rowena Drake, whom he observed murdering his sister.

While appearing to be a good person, she's killed a little girl and has taken part in other murders.

Bitch in Sheep's Clothing: Rowena Drake is a marvelous example.

Big Damn Heroes: Nicholas and Desmond rush in to save Miranda from being poisoned by Michael Garfield.

Big Bad Duumvirate: The murderer is part of one, who by the end of the story have racked up a staggering four murders together, possibly including a fifth.

Attention Whore: Joyce is known to tell fabricated stories for attention.

Prior to the story's beginning you had Leslie Ferrier, a womanizer and a forger.

Her younger brother Leopold, a blackmailer, also counts. Joyce manages to be a prepubescent version of this trope, being regarded by most of the adults and children around her as a lying attention-seeker and not incredibly well-liked as a result.Arc Words: 'Ding dong Dell, Pussy's in a well.'.

The '60s: Takes place in the decade, with Desmond explicitly being described as wearing period-appropriate attire.
