We’d puzzled over PHIAL and HARRISON too, so thanks for the explanations.
Please can anyone explain 50d?
Proceeded with caution and replaced one’s diamonds (5)
The answer looks like NOSED, but I can’t fully see why.
Also, is it just me, or does anyone else think 48a contains a mistake? The clue reads:
Cook’s odd selections from statuettes (5).
The answer is SAUTÉ, being the odd-numbered letters of STATUETTES. In which case, isn’t the ‘s in COOK’S redundant? The clue would make much more sense without it.
