"Software millionaire Joe Tesla is set to ring the bell on Wall Street the morning his company goes public. On what should be the brightest day in his life, he is instead struck with severe agoraphobia. The sudden dread of the outside is so debilitating, he can't leave his hotel at Grand Central Terminal, except to go underground. Bad luck for Joe, because in the tunnels lurk corpses and murderers, an underground Victorian mansion and a mysterious bricked-up 1940s presidential train car. Joe and his service dog, Edison, find themselves pursued by villains and police alike, their only salvation now is to unearth the mystery that started it all, a deadly, contagious madness on the brink of escaping The World Beneath."--Amazon.com.
