I think this one contains some of the best and most important stories (they start blending at some point).
I have to admit that I still could not stop. There are quite a few discrepancies between the books, but I don't think that distracts from the fact that they are so much fun to read. They might generally all be quite similar, but they are like the best of The Mentalist, Lie to Me and CSI combined. There are so many stories in each book (save the first), that I can't choose a favourite or rate them separately. Sir Arthur Conan Doyle was a singularly brilliant author and people will try to copy him till the end of time. I just wish I had read printed, properly proofread copies of the books so that I didn't have to be distracted a clearly unproofread version of these classics.
