One, Two, Buckle My Shoe

Lore & Background

In the Poirot universe, cases carry titles that evoke the specific puzzle at hand—the Orient Express, the Nile, the ABC murders—each one a small key to the social or mechanical lock Poirot must pick. 'One, Two, Buckle My Shoe' fits none of those patterns. The tone is hard-boiled, the protagonist is a man in a rumpled suit, and the method is street-smart intuition rather than the meticulous ordering of a small grey brain. Fans occasionally stumble on the title in mislabeled fan-fiction indexes, confused anthology PDFs, or AI-generated 'Poirot case lists' that conflate every detective story with Christie's most famous sleuth. The encyclopedia records the correction here so the shelf stays tidy.

In Their Own Story

The library at 5B Baker Street—no, at the small flat in London where Poirot keeps his morning routine intact—holds a misfiled card in the index drawer. The card reads 'One, Two, Buckle My Shoe' in a hand that is not Poirot's. He turns it over, frowns at the smudge of cheap ink, and slides it into the 'Not Mine' pile beside a torn movie poster and a crossword he never finished. 'Order,' he murmurs, tapping the card with one manicured finger. 'It is not in order. And it is not mine.' He returns to his moustache and his small, neat world.

Reader's Guide

There is no central mystery to outline because the title does not belong to a Poirot case in any published or adapted work. There is no locked-room, no alibi construction, no social-drama tableau of a country-house dinner. If you are looking for a Poirot case with a counting or nursery-rhyme structure, you may be thinking of 'The ABC Murders' (alphabetical) or 'The Hound of the Baskervilles' (which is not Poirot at all). The method here is: verify the title, check the author, and file the card under 'Not Mine.'

Did You Know?

• The title comes from the traditional English counting rhyme 'One, two, buckle my shoe; three, four, knock at the door…' and has no established connection to Agatha Christie's bibliography.
• Poirot's cases in Christie's novels and authorized adaptations number roughly 33 long-form and 10 short-form stories; none carry this title or a close variant.
• The phrase 'buckle my shoe' in the rhyme refers to the old practice of fastening a strap over a shoe, not to a modern lace or buckle.
