I watched this CFF movie for kids on German TV way back in the late 1960's and am hoping till this day that it will get released on DVD. All I remember is that it was filmed in Scotland next to a castle and it was quite suspenseful. I enjoyed it very much and when German TV channel Pro7 aired many old CFF films again in the winter, spring and summer of 1989, I was hoping and waiting for this one and for "Fourwinds Island", but in vain. By the time I had written to Pro7 and received an answer, they had already changed their format and from that time on it was all new TV productions. Too bad!
