This was a hard book to rate. In many ways, it delivers on all of the promises any Alan Furst novel offers. The research appears to be top notch, with plenty of telling details to give it a powerful sense of place; the story puts the reader in the middle of the hidden side of the road to WWII. Yet, I got the the last 20 pages wondering where the novel was going? Alas, I don't mean an unexpected plot turn thrilled me with the unknown. Rather, the plot doesn't seem to suggest an ending. While Furst provides an ending, it felt more like a petering out that a climax. I suspect the problem is that the plot hinges on a secondary character who isn't well-enough developed to make the end feel crucial. Her fate never seems in question, so the reader (or at least I) doesn't invest in it as the novel progresses.I wouldn't suggest a dedicated Furst fan should skip this one. Enough of Furst's charms are on display to make it worthwhile. But if you are new to his oeuvre, he has many other novels that offer a vitality from beginning to end. Having read five of his novels, Dark Voyages is the one that haunts my memories.
