Pound discovered in a bath robe (5)

I believe the answer is:

throb

'pound' is the definition.
(I know that throb is a type of pound)

'discovered in a bath robe' is the wordplay.
'discovered' indicates a hidden word (remove the letters covering the answer in the clue).
'THROB' can be found hidden inside 'in bath robe'.

(Other definitions for throb that I've seen before include "Pulse" , "Pound" , "Drum" , "Vibrate with rhythm like heart" , "Martin -; Kingsley -" .)

I've seen this clue in The Guardian.
