Men In Black has to be one of the most mysterious aspects of the whole UFO phenomenon, and a book on this subject is long overdue. Jenny Randles is always a reliable author, and she doesn't let us down here. She gives a lot of background to some cases that are quite famous in the UFO area, but aspects of which aren't that well-known. For instance, I didn't realise that there is a lot more to Kenneth Arnold's experiences than him simply sighting the first 'flying saucers' in 1947. I feel that the book could have benifited from some illustrations, as Ms Randles often refers to pictures, and it would have been nice to have seen them for ourselves. I was also quite surprised she didn't mention the Blairgowrie incidents of 1985 (which are detailed in Ron Halliday's book on Scottish UFOs "McX"), which are, for me, one of the most wierd tales of the MIB to come out of these islands. And some more detail on the Broad Haven flap of 1977 would have been nice, although as most UFO writers seem to ignore that one entirely, I was just pleasently surprised that she mentioned it at all! Plus there is no mention of Ted Holiday's sinister experiences with the MIB at Loch Ness in the early 1960s. But perhaps I'm just nit-picking. This is Randles's book after all, and she writes about the cases she knows well. And after reading this, the Mothmen case seems more dark and terrifying than ever!
