And catch a fox and put him in a box and never let him go

The refrain “And catch a fox and put him in a box and never let him go” turns a children’s rhyme into a moral image in The A.B.C. Murders. Heard by Hercule Poirot and Arthur Hastings as they pass a ring of singing children, it returns at the novel’s resolution as Poirot’s description of what Franklin Clarke has done to Alexander Bonaparte Cust: not simply to commit murder, but to condemn an innocent, vulnerable man to a living death by making him believe he is the killer.

The rhyme and its first appearance

The words first reach Poirot and Hastings while they are returning towards their car. The children sing the refrain in shrill, untuneful voices; Poirot cannot make out the words until Hastings listens and repeats them. The nursery image is simple and almost playful on its surface, but its promise is stark: the fox is caught, put away, and never released.

Poirot repeats the line, and his expression becomes grave and stern. The shift makes the rhyme more than a passing detail of the roadside scene. Its pattern of capture and permanent confinement gives shape to a cruelty that the investigation has not yet fully explained, and the novel lets the children’s words linger before turning back to the case.

Poirot’s interpretation of the fox

Hastings begins to explain the rhyme as a chase in which hounds follow the fox and eventually catch it. Poirot rejects the suggestion that the fox could enjoy such an outcome. He contrasts a quick death with being shut away in a box forever, judging the latter the worse fate. The distinction is central to his response: the rhyme’s menace lies not only in capture, but in the duration and helplessness of captivity.

After shaking his head, Poirot abruptly changes the subject and says that he will visit Cust the following day. The transition connects the rhyme’s image of confinement with the case’s human consequences. At this point, the association is left suggestive rather than fully explained; its meaning becomes explicit only after the investigation has exposed the part Cust has been made to play.

The hunted animal and Cust’s confinement

In the final account of the crime, Poirot describes Franklin Clarke’s conduct after the murders through the image of a hunted animal. Clarke returns to his London lodgings, where he is known and believes himself safe, while others think he has been in Cheltenham. He still has the murder knife with him and hides it behind the hall stand. When he is warned that the police are coming, Poirot calls this the hunted animal’s last run.

Poirot also explains Cust’s journey to Andover. Cust has no money left and is worn out; he goes there, Poirot suggests, from a morbid desire to see the place of a crime he believes he committed, though he can remember nothing about it. His feet finally lead him to the police station. The detail recasts the apparent confession and surrender: Cust is not the successful hunter of the rhyme, but a man driven by exhaustion and a false belief about his own guilt.

The rhyme’s moral meaning

When Hastings recognizes the connection, he says that Poirot had told Cust that his crime was not sporting. Poirot confirms the point, calling the crime abominable not so much because Clarke murdered his brother as because he subjected an unfortunate man to a living death. He repeats the fox refrain to name that cruelty. The image now describes a deliberate human act: Clarke has trapped Cust in fear, guilt, and the conviction that he committed murders he cannot recall.

Megan Barnard responds with a deep sigh and asks whether the account is true. Her reaction marks the moment when Poirot’s explanation lands not as an abstract deduction but as a revelation of what has been done to Cust. The refrain therefore binds the novel’s two kinds of pursuit together: Clarke’s effort to control the investigation by making Cust its apparent culprit, and the lasting psychological confinement imposed on the man who is caught in that design. It is the difference between a chase that ends and a box from which the captive is never allowed to escape.
