Lancashire city not reaching conclusion quickly (6)
I believe the answer is:
presto
'quickly' is the definition.
(I've seen this before)
'lancashire city not' is the wordplay.
'lancashire city' becomes 'prest' (I can't justify this - if you can you should give a lot more credence to this answer).
'not' becomes 'o' (I've seen this in other clues).
'prest'+'o'='PRESTO'
'reaching conclusion' is the link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for presto that I've seen before include "scored quickly" , "quick to score" , "hey......,cries the magician" , "(Musically) fast" , "quickly in bars" .)
