The reason I'm only giving this 3 stars is that the quality of the stories is rather uneven, IMHO.
Of the 13 stories in this anthology, I really liked "A Woman's Place" best of all. "The Small world of 221B", and "An Innocent Icarus" are the other two contenders. The rest, unfortunately, is filler. That said, the book is worth borrowing, if only for those three stories, which are superbly crafted and clever.
