Hi, dear teachers. It's me again.
What do 'quiet pockets' mean in the sentence:
There are many quiet pockets, unknown to almost all but taxy drivers who traverse them with expert knowledge... Agatha Christie
Thanks in advance. Still got mad love for you.
With the context of the taxi drivers, this must be a reference to driving through London (in the days when it was possible). Taxi drivers in London, who have "the knowledge" [are trained intensively in the geography of London] know all sorts of ways through the back streets to avoid the main roads which are busy. These can be seen as "pockets [small areas] of quiet".
