If you like Alfred Hitchcock this one needs to be seen. There is a great cast and a complex story line. A simple con game leads to a long kept secret. A secret which would be a windfall for one character but endangers others who wish to profit from the discovery. There are parts which have you holding your breath waiting for the suspenseful next step. Only to have a twist which leads to watching more intently to figure out what is next. There are quite a few scenes in different locations. There are as many outside scenes as indoor. I would recommend watching this Hitchcock classic.
