I already have the Collector's Library's, "Complete Sherlock Holmes" edition - which contains all of the short stories and four novels together, as well as hundreds of wonderful illustrations by Sidney Paget throughout. However, that edition, while beautiful, is just too bulky for me; hence my reason for buying this set.
Other reviewers have brought up the size of the books, and I'll agree they are smaller than the picture suggests, but for me that's a plus point. It's essentially a mantelpiece collection which you can easily draw from and comfortably hold your chosen book in one hand. The size of the text itself is in no way compromised by that; in fact it's easier to read as there are only eight or nine words across each page (meaning the eyes have less distance to travel and thus less strain). We all know how masterful Doyle's writing is, so I'll assume that's a given and just rate the specifics of this product (A+ = Perfection, F = Abysmal):
Paper quality: A
Print quality: A
Bind quality: A+
Sleeve quality: A+
Overall design: A+
(Also to note: the containing box is strong and stylish, each book contains an attached thread bookmark, and all of the pages have gold-gilded edges.)
The current price on Amazon.co.uk is £21.54, which I'd suggest is an excellent bargain (I'd be willing to pay twice that). This fine six-piece box set is a must have for anybody wanting to own Doyle's literary masterpiece in its entirety but without the restrictive nature of a bulky one-piece edition.
