Midnight Lace (1960)

Kit and Anthony Preston never had a real honeymoon, and the midnight lace pajamas are for when they can finally get out of London. Anthony's business is very pressing these days. Then Kit is frightened one day in a London fog by a voice behind a statue. Next the telephone calls start. Then there is a new man on the block, the architect of a building going up next to the Prestons' vintage apartment. That vintage building has the kind of curving stairwell and cage-type elevator that Hitchcock and other suspense masters have loved. Could Kit merely have an overactive imagination?
