The British Government had "Men in Black" such as wing commander Myles Formby investigating people who claimed to have had strange encounters and this is explored in Jenny's readable book "The truth behind the men in black". Further to this The Ministry of Defense took the time to look into the case of the 'Cumbrian Spaceman and Fireman Jim Templeton' and Jenny reviews such cases as these in this book. A lot of other cases are reviewed, warts and all, including accounts by former British Police Officers such as Alan Godfrey and 'Philip Spencer'. Having taken on-board descriptions of abductions and contacts you are naturally awaiting a logical conclusion to what is being reported. Alas, Jenny presents several solutions. You can judge for yourself given the information between the covers, "what is the most likely scenario?". For those readers who would like explore the possible root causes, then look no further than "The complete Book of Aliens and Abductions" also by Jenny.
