can anyone give me a clue for
31 Legal notes made in error about Moriartys assistant (9)
46 The old man took no tea with sugar (7)
61 Ancient city where Syrians went to a chinwag (7)
Thanks to those who gave me hints. I can see only one word for for the food in 51 and I understand the 'fast' part; I presume 'poor' refers to an anagram of an abbreviation for 'pensioner' but I don't see the neeed for 'old'.
