I've always enjoyed reading Sherlock Holmes, but I have to admit I've never had the good fortune of reading any of these. Can I borrow yours? ;-p
Anyhow, your high praise has me intrigued -- I love a good mystery in any medium, I enjoy good B&W artwork, particularly in settings like this, and...it's Sherlock Holmes! I don't know how soon I'll be able to start tracking these down (my poor wallet is still doing some recovering) but I'll definitely put these on the "to get" list.
Dang, today (10/31) would've been an appropriate day to start reading!
"Go Get 'Em Cap!"
I hope you can find them. A friend of mine is trying to get them ordered right now, and while I'm sure volume 2 is available, volume 1 might be difficult. If he has success, I'll let you know.
