Sherlock Holmes is called upon to investigate two aerial mysteries; the strange death of a balloonist, and the unexplained crash on launch of Professor Samuel Langley's Aerodrome. Employing his astonishing powers of observation and logical reasoining to the full,  Sherlock Holmes brilliantly solves both mysteries. In the process Holmes gives Doctor Watson lessons on lighter and heavier than air flight, and Watson is astounded by the extent of Holmes's aeronautical lnowledge. Professor Langley believes his steam driven flying machine will be the first to fly, and "conquer the heavens," but Sherlock Holmes favors the Wright brothers, Wilbur and Orville Wright, who employ a gasoline engine.

In reward for his services, Langley gives Sherlock Holmes a generous honorarium, and a plaque announcing that Holmes is an "Honorary Aviator," along with an aviator's cap and goggles..Holmes is amused, and informs Watson that he likes the idea of being an aviator. So ends the case of  "Sherlock Holmes and the Flying Machine," historically accurate and written in the style of Sir Arthur Conan Doyle, with five illustrations. If you like reading about Sherlock Holmes, and things aeronautical interest you, then you will love this book. Only $3.99.
