A large podium, studded with microphones, had been erected on the Great Lawn, directly in front of the administration building. Before it had been set some three dozen folding chairs, on which sat reporters from local newspapers, the Times of London, Nature magazine, Oceanography, Time, and a host of others. To the right of the podium were two television cameras, one from the BBC and the other from CNN. To the podium’s left was a large wooden scaffold, upon which sat a large, strange-­looking machine of dark metal: a cross between a cigar tube and a pincushion, about thirty feet long, with a bulky attachment protruding from its upper edge. The restless chatter among the reporters grew muted as the main doors to the administration building opened and two men stepped out into the September afternoon sunlight. One was plump and short, with a shock of white hair and wearing a thick tweed coat. The other was tall and quite thin, with rather severe features, light brown hair, and alert gray eyes. Unlike the first man, he was dressed in a conservative dark suit. The two approached the podium and the older man cleared his throat. “Ladies and gentlemen of the press,” he began, “thank you for coming. I am Colin Reed, provost of the Glasgow Institute of Science, and to my right is Jeremy Logan.” Reed took a sip from a glass of water on one side of the podium, cleared his throat again. “You may well know of Dr. Logan’s work. He is perhaps the only, and certainly the preeminent, enigmalogist operating in the world today. His job is to investigate, interpret, and explain the—­for lack of a better word—­unexplainable. He throws light upon riddles of history; he separates myth from truth and the natural from the supernatural.” At Reed’s side, Jeremy Logan frowned slightly, as if uncomfortable at this bit of panegyric. “About two months ago, we contacted Dr. Logan on his home ground of Yale University and asked him to undertake an assignment for us. That assignment can be briefly explained: to definitively prove, or disprove, the existence of the creature popularly referred to as the Loch Ness monster. Dr. Logan has spent the last six weeks in Inverness, doing precisely that. I will now ask him to share his findings with you.” Reed stepped back from the microphones and Logan approached. He surveyed the crowd of reporters for a moment, then began to speak. His voice was relatively low and mild, the mid-­Atlantic accent contrasting with Reed’s Scottish burr. “The Loch Ness monster,” he began, “is the most famous of all the supposed Scottish lake monsters, perhaps the most famous of all cryptids.
