Morphology

fox + in + the + henhouse

The literal image of a fox inside a henhouse (a predator among vulnerable animals) directly conveys the idea of a dangerous intruder in a vulnerable setting; combining 'fox' + 'in' + 'henhouse' therefore yields the intended figurative meaning. This animal-predator metaphor is transparent and common across languages, so a B1 learner who knows the constituents can readily infer the MWE's meaning.

Etymology

Fox in the henhouse comes from the image of a wild fox sneaking into a henhouse to attack helpless chickens. So, calling someone a fox in the henhouse means they are 'a danger' placed inside a group or place where others are trusted or weak.
