Puma store managed to be a longest running show in London (9)
I believe the answer is:
mousetrap
'be a longest running show in london' is the definition.
I can't judge whether this defines the answer.
'puma store managed' is the wordplay.
'managed' indicates anagramming the letters.
'puma'+'store'='pumastore'
'pumastore' with letters rearranged gives 'MOUSETRAP'.
'to' acts as a link.
Can you help me to learn more?
(Other definitions for mousetrap that I've seen before include "Cheese-baited snare" , "This may take the Mickey" , "Poor cheese (colloq.)" , "Poor-quality cheese" , "Anti-rodent device" .)
