British specialist in information technology Vic Tandy says he will never forget that night. He was working overtime in his laboratory at the University of Coventry, England. The clock showed 7 p.m. All of his colleagues had already left yet Tandy seemed to have lost the sense of time because his work absorbed him completely. All of a sudden he felt cold sweat running down his back – he could feel somebody watching him. He looked around and saw something gray, fog-like and somewhat shapeless moving closer in his direction. It was apparently moving and looking right at him. The apparition vanished in thin air when it was just couple of feet away from Vic. The researcher cursed loudly, took a deep breath, and wiped the sweat from his face.The above is just the beginning of a story relayed by Tandy to one of the British dailies. The remaining part unfolds like a detective movie interspersed with scientific details.
Being a true researcher, Tandy decided to do research on the phenomenon and place it on the solid scientific grounds. Having become a “ghost buster” of sorts, he spent five years looking into all the stories related to ghosts observed in the old English castles. He lay in wait at night. He studied the readings of scientific equipment. Eventually, he learned from whence the ghosts came. He even put forth the reasons why the English happen to witness ghosts more frequently than the residents of other countries.
