Bon Matin, HMEssex,
Referring to your ultimate sentence, how does one qualify the word 'savvy'?
It was one of my late Mother's most commonly quoted questions of qualification of a person. She used it in the nuance of common sense, rationality, or more commonly - 'being Streetwise'.
How would you rate DS 'Stan' Brian Jones in the 'savvy' stakes?
Moreover, as I understand from things you have posted on, that you are domiciled in the area N of the Blackwater, you will (and 'and I will say' this only once!) comprehend me when I ask, "Is he still 'coaching'"?
Everytime I see one of the omnibuses, I muse on whether 'Stan' is still living, in the 'Land of the Tolles'.
