I don't agree that the Garrett books are 'very hard to find'. Over the last 2+ years when I've been haunting used book stores in my area I've found several copies of each book except _Dread Brass Shadows_. In fact I found 3 copies of the first Garrett book within a 3-week span, two of them for 25 cents each. They weren't in great condition, but they made some Cook fans happy. You've just got to know where to look.
