Movie from 60s or 70s, blond teenager w cat mystery
Hi, guys. Searching for a movie made in the late 60s early 70s about a teenage girl with a blond ponytail who gets involved in a mystery involving some asian bad guys putting a dead guy in a meat locker and I think there was a bad grownup man she knew. She would write anonymous letters to the bad guys I think and sign with her kitty's paw dipped in ink. Seems like she had a male relative that was a detective or something like that. Thanks, hope someone knows what I'm looking for. :)
