Watched this on Amazon prime. The basic plot is a group of twenty-somethings get bored at a party and decide to explore a deserted mansion (amazingly, horror plots haven't changed much in 50 years). I would best describe this as a horror whodunit movie, although the horror is milder than some Hammer House productions. Typical for a 'B' horror flick, you always find famous actors either at the beginning or end of their careers. The Police Detective is played by Dennis Price, who gained fame for the Ealing Comedy 'Kind Hearts and Coronets' alongside Obi-Wan Kenobi and two of the explorers are Frankie Avalon and Richard O'Sullivan who became a big UK TV star. The movie starts incredibly slowly but gets a lot better, the plot has a couple of twists and the ending might surprise you. Good for a horror fest.
