This one contains some of the most famous stories of the Sherlockian canon (such as A Scandal in Bohemia, The Speckled Band, and The Red-Headed League), but it has also its fair share of the less brilliant. Five Orange Pips is certainly lame; everyone acts stupidly there, starting with the criminals and ending with Holmes himself, and the most notable piece of investigation is consulting a dictionary.
I have of course read the stories before, but couldn't be bothered to rate them separately, so here's the rating for the collection: "liked it".
