Second in the I Love a Mystery series sees Jack Packard (Jim Bannon) and Doc Long (Barton Yarborough) investigating a mystery involving a missing man, shrunken heads, and blow guns. Yarborough is at his "good ole boy" best, for those who enjoy him. Bannon is not bad but not exciting. Very ordinary. Anita Louise is irritating throughout the picture. Terribly overwrought performance. The best thing about this series were the nice atmospheric moments. The usage of supernatural or bizarre elements helps separate it from most other B detective films. The killer is pretty easily figured out, though the motivation was pretty cool. Anita Louise's hysterics are the worst part of the movie. Still a decent way to spend an hour and change.
