26a Stop and Chat (5) S _ E _ K
(It must be SPEAK, but why stop?)
4d Most of the school is in old Chennai (6) _ A _ R _ S
It must be MADRAS (old Chennai) but why the rest?
15d Reprise d'enfant mange par bete noire (10) R _ P _ T _ T _ O _
It must be REPETITION (rather than reputation) and I think it is because "petit" = "little one" (enfant) in an anagram of "noire" and definition = reprise (repetition)... "mange" means eat therefore "noire" surrounds "petit". Is my logic correct ?
