Glad you got there. A mutton is a long dash, the width of a letter em, and a nut is a short dash, the width of a letter en in printing. It’s worth remembering, as they crop up occasionally
I don’t much like it, but I think it must be an American phrase meaning to investigate thoroughly, gaining complete knowledge of. Five letter word for watch, as in a Boy ?????, pocketing a word for plain, frank, missing its final letter.
Quisling, I expect your answer may be correct - but if it is, it's one of the worst clues I've seen for quite some time! The surface reading is awful and the answer - if it's correct - really does seem a bit of a stretch.
I quite agree, Malone. The definition is sketchy, and the surface terrible. It’s only the plural pockets which almost forces the wordplay to be as I described. I find Bharat’s clues grimly fascinating, like a verbal car crash sometimes. I hope they’ll enlighten us on whether my speculation was correct!
