Password Kill Agent Gordon (1965)

Rosalba stars with Helga Line ( who gets the bigger role here ) as a dance who briefly gets mixed up with film's stiff hero.  He sneaks into her bedroom and tickles her foot with a feather to get her to spill her guts.  Rosalba enjoys a much needed smoke afterwards.
Still a small role but the bigger, juicier parts were about to start filtering in.
