Literary adventurer disturbed lingerer grabbing tool for opening letter (9,6)
I believe the answer is:
peregrine pickle
'literary adventurer' is the definition.
(character created by Tobias Smollett)
'disturbed lingerer grabbing tool for opening letter' is the wordplay.
I cannot really see how this works, but
'tool' could be 'pick' (pick is a kind of tool) and 'pick' is found within the answer.
an anagram of 'lingerer' is 'regrinel' which is present in the remaining letters.
'letter' could be 'pe' (pe is a kind of letter) and 'pe' is present in the answer.
A single letter 'e' remains which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Another definition for peregrine pickle that I've seen is " Smollett character".)
