For the world’s most brilliant criminologist, every mystery has a solution His name is Professor Augustus S. F. X. Van Dusen, but to the newspapers he is known as “The Thinking Machine.” Slender, stooped, his appearance dominated by his large forehead and perpetual squint, Van Dusen spends his days in the laboratory and his nights puzzling over the details of extraordinary crimes. What seems beyond comprehension to the police is mere amusement to the professor. All things that start must go somewhere, he firmly believes, and with the application of logic, all problems can be solved. Whether unraveling a perfect murder, investigating a case of corporate espionage, or reasoning his way out of an inescapable prison cell, Van Dusen lets no detail elude his brilliant mind. In this highly entertaining collection, featuring many of the stories that made The Thinking Machine a national sensation, ingenious criminals and ruthless villains are no match for an egghead scientist.
