Il y a anguille sous roche
Meaning: Something suspicious is quietly going on beneath the surface.
Literally: There is an eel under the rock
Example: “Ils se taisent dès que j'arrive, il y a anguille sous roche.” — They go quiet as soon as I walk in; something fishy is going on.
English equivalent: Something fishy is going on
Origin: An eel hiding under a rock cannot be seen, but it is there, and it is slippery: something is being concealed. Wiktionnaire dates the phrase to 1563 and traces it to Virgil's Latin latet anguis in herba, "a snake lurks in the grass," which French turned into an eel under a rock. The Académie française's first dictionary (1694) already has il y a quelque anguille sous roche, "there is something hidden."
