Swordsman regularly on call visiting ladies? (8)
I believe the answer is:
damocles
'swordsman' is the definition.
(as in the sword of Damocles)
'regularly on call visiting ladies?' is the wordplay.
'regularly' means one should take alternating letters (regularly take one letter, leave next etc.).
'visiting' indicates putting letters inside.
'ladies?' becomes 'dames' ('dame' can be a synonym of 'lady').
'on'+'call'='oncall'
The alternating letters of 'oncall' are 'ocl'.
'ocl' going into 'dames' is 'DAMOCLES'.
(Other definitions for damocles that I've seen before include "He sat under a sword" , "Nervous diner" , "Character associated with suspended sword" , "Greek courtier" , "whose sentence was suspended?" .)
