The Adventure of the Six Napoleons and Other Cases (The Penguin English Library)

Many readers would claim that The Adventure of the Copper Beeches or The Man with the Twisted Lip was their favourite Sherlock Holmes story - but then that would be doing an injustice to The Adventure of the Yellow Face and The Problem of Thor Bridge. It is just as well that in the end we do not have to choose - as if we did then there would be no doubt it should be The Adventure of the Six Napoleons.
