There is no Book-cover . There is also a little writing on the first page. Book overview The first of "rediscovered" Sherlock Holmes adventures, THE SEVEN-PER-CENT SOLUTION is now a new classic. These reminiscences of John H. Watson, M.D., recount the unique collaboration of Holmes and the equally great detective of the human psyche, Sigmund Freud, as they solve a mystery on which the lives of millions may depend. "What splendid book, what grand fun! A corking good read and a crackling good adventure that performs the delicious miracle of bringing back to life the greatest detective of them all."
