I read this book for my book club & we had an interesting discussion on the history of the building, "The Dakota". This novel includes mystery, historical fiction & a lot of drama covering characters in two time frames, the 1880's and 1980's. The stories are brought together in the end in a surprising conclusion(at least to me). This book would appeal to those interested in New York City history, in particular its architecture. The treatment of the mentally ill would also be of interest.
