Salome's stepfather (5)
I believe the answer is:
herod
'salome's stepfather' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for herod that I've seen before include "Infanticidal king" , "Biblical king of Judaea" , "King of Judea in the time of Jesus" , "Old king" , "Royal baby-killer" .)
