Death of a Ghost

Frequently when I read a Golden Age mystery I find myself partway through wondering if I have read it before. I don't know is this is because: A. I have actually read it before, or B. These books tend to be predictable and samey, so that one reminds me of others that I have read and I can't keep them straight.

I definitely had the feeling with this one; I didn't think I had read it before, but once the denouement began to unfold it began to feel so familiar.
