I believe the answer is:

mace

I'm a little stuck... Click here to teach me more about this clue!

'club' is the definition.
(I've seen this before)

I don't understand how the rest of the clue works.

(Other definitions for mace that I've seen before include "Came to find ceremonial staff" , "Ceremonial staff or kind of spice" , "Spice; heavy club" , "Ceremonial staff of office" , "One of 9 [CLUBS]" .)

I've seen this clue in the Evening Standard.
