My GoodRead review: "Great mystery and suspense, with some frustratingly drawn out areas. The resolution seemed a bit anticlimactic, but I did find the actual ending to be very interesting. I wonder if it was purposely left open for the possibility of a sequel that, unfortunately, was never to come.
All in all, it was a good read."
I found that the first 12 chapters went along at a good pace, building, and twisting just enough - but then...blah! Things began to get slow, and plodding until around chapter 17 or 18, when it picked up again. I was most, excited (for lack of a better word) while reading chapter 20, wondering what was going to happen with the two of them (Bridget & Sam) but it seemed to fall flat; I was expecting a little more oomph, in the resolution.
I am happy to hear that there were other Sam Spade stories, though, and I will look them up.
