Assassin’s track after boarding public transport (6)
I believe the answer is:
brutus
'assassin's' is the definition.
'track after boarding public transport' is the wordplay.
I cannot quite understand how this works, but
'track' could be 'rut' (rut is a kind of track) and 'rut' is found within the answer.
'transport' could be 'bus' (bus is a kind of transport) and 'bus' is found within the remaining letters.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for brutus that I've seen before include "statesman who committed suicide in Macedonia" , "One of Julius Caesar's assassins" , "senator in Rome once" , "one associated with a conspiracy long ago" , "legendary hero" .)
