He might haul faulty double-decker buses to old jail? (5,2,6)
I believe the answer is:
tower of london
'he might haul faulty double-decker buses to old jail?' is the definition.
The definition suggests a singular noun which matches the answer.
'he might haul' is the wordplay.
I cannot really understand how this works, but
'he' could be 'lon' and 'lon' is located in the answer.
'haul' could be 'tow' (tow is a kind of haul) and 'tow' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for tower of london that I've seen before include "Home to the UK's Crown jewels" , "Fortress on the Thames" , "Where to see crown jewels" , "Building" , "Where the Crown Jewels are kept" .)
