When I was a teenager, I went through a period when I was addicted to murder mystery novels from the 1940's. Because these were readily available at used bookstores, I own quite a collection of them, including several by Charlotte Armstrong. One of these is The Unsuspected, written in 1945. It wasn't until sometime later that I realized there was a movie based on the novel, filmed in 1947 and starring Claude Rains, Audrey Totter, Joan Caulfield, Constance Bennett, and Michael (Ted) North. I didn't get around to seeing the film until last year; while it's not my favourite film noir, it is definitely worth watching. One reason for this is the cinematography: this is a gorgeously shot movie, reminding me at times of The Naked City. It must be admitted that all of the acting isn't the best, especially that of Michael North. This was, I think, his first- and last- starring role in a film, and soon after this he left acting and became an agent. Audrey Totter as Althea is, however, delightfully catty and Claude Rains is amazing as Victor Grandison, the unsuspected one.
