Written by Gardner F Fox in 1975 under the pseudonym Glen Chase. Always on Sunday is about a female Mafia crime-fighter, Cherry Delight, who uses her sex to slay the bad guys. This is her twentieth mission. In this caper she is set upon by a couple of Greek colonels who are monsters, dope fiends and sex-niks. Any other girl might be dismayed - but Cherry just takes them as they come.
