This is the third of Cara Black's Aimee Leduc novels, and the fourth one I have read.In this outing, Leduc is looking for her long-missing mother ... because people keep coming by and alluding to her. Unfortunately, just about everyone who comes by and alludes to her mother winds up dead in fairly short order.There are side plots involving art theft and, of course, the murders.As with the other books in the series, there are more twists and turns in the plot than in the Latin Quarter's alleyways. And, once again, the "whodunnit" was a surprise. Because I read a great many mysteries, it's hard to get one past me -- but Black has done so consistently.I always enjoy these books, not only because of my love for Paris but because of Black's multidimensional characters. We get a look at how the villains got to be the way they are, and even the "good guys" are flawed.
