A riddle that has been bugging me for 20 years or so was just solved today! I vaguely remembered a Japanese mystery series being shown on the telly in the early 70s. I saw it being mentioned in a magazine around 15 years ago, but that was still years before I could search for it on the web. So the name was gone again, until one humble folk helped me out today! It´s Kaiki Daisakusen and it looks like the originals have been released on DVD in Japan. Sadly I don´t speak any Japanese and ordering it from there costs good money. We´ll see...
