Rip-roaring whodunnit... Lot of elements; from Sleuth and the mystery writer / plot controller, to Murder On the Orient Express "did everyone do it - and excessively accented detective", and much more. Yes the house itself is also a character in this one...
If you live in the Boston area and want to see this properly you HAVE to see it at Fine Arts in Maynard. A piece of the plot revolves around a car chase and more along Maynard's Main Street. And if you have seen the movie, yes those stores on the right are real.
Also! There is a fantastic Grey Gardens-styled "great nana" character who keeps popping up. Fur and tweeds. Indoors. Key.
