The Adventure of the Engineer's Thumb and Other Cases

The Penguin English Library edition

As usual with the Sherlock Holmes stories it is very hard to say which are the best - but there are many stories here which would get the vote - ranging from The Boscombe Valley Mystery to the wonderful Adventure of Silver Blaze, from the Adventure of the Norwood Builder to A Case of Identity, but above to the uniquely strange and macabre Adventure of the Engineer''s Thumb.
