This is a relatively short book from Bill Tilman, and not one I would recommend to the casual reader. Tilman led the 1938 British Mount Everest attempt - unsuccessful, of course, and in this book he describes it in detail.
To join his expedition he invited Eric Shipton, Frank Smythe, Noel Odell, Peter Lloyd, Peter Oliver and Charles Warren. Ang Tharky was sirdar, Tensing Norgay one of the Sherpa's and Karma Paul was interpreter and general problem solver.
This expedition was known for cutting away the excesses of previous attempts - famously this one had a budget of £2500 - just a quarter of the budget of the previous Everest expedition. He explains all the preparations in detail, the thinking and planning and using the dairies of others fills in the events he wasn't personally in volved in.
There is much to like about a brief explanation of the expedition, irrespective of its failure to summit. It firmed up thinking about the North Col route (which they investigated); confirmed the monsoon season was not a viable time to attempt a climb; demonstrated a small party was sufficient to make a valid attempt to summit (Tilman's seven rather than the larger parties that has been favoured in previous attempts); and provided some further testing of oxygen apparatus (albeit with unclear results).
Tilman also proves what a student of climbing history he is. Making multiple references to different expedition attempts, decisions made and opinions on many matters related to this expedition.
Interestingly, this was to be the last attempt on Everest from Tibet. World War II was brewing, and Tibet was soon to be occupied by China, so future attempts were made from Nepal, including the next expedition, in 1953, which we know was successful!
