Red Thumb Mark

The mysterious fiction, The Red Thumb Imprint, describes the story of the valuable diamonds that are missing, and the thumbprint of Reuben Hornby is found in a drop of blood on a piece of paper at the lower part of the safe. The specialists of Scotland Yard are all in agreement. Apparently, this is an obvious situation. Or, on the other hand, is it? For reasons known exclusively to himself, Dr. John Thorndyke feels a little unsure about the authenticity and starting origins of the evidence. Now he should make his case in open court, utilizing the most recent techniques of Edwardian science to prove the honesty of a young man. Will he succeed, or will the case of "The Red Thumb Mark" end up being his first as well as his last case? This book is filled with thrills and adventure, which makes it worth reading for all thrill readers.
