Woolrich and seven things that could add up to murder

I just finished reading "REAR WINDOW" by my favorite author, CORNELL WOOLRICH.
ALFRED HITCHCOCK based his famous film on the story, in which an immobile protagonist watches his neighbors' actions through his back window.
After watching one neighbor seemingly ignore his ill wife and later struggle with a trunk, the protagonist lists seven things that, for him, add up to a possible murder:
1. The lights were on all night the first night. 2. He came in later than usual the second night. 3. He left his hat on. 4. She didn't come out to greet him -- she hasn't appeared since the evening before the lights were on all night. 5. He took a drink after he finished packing her trunk. But he took three stiff drinks the next morning, immediately after her trunk went out. 6. He was inwardly disturbed and worried, yet superimposed upon this was an unnatural external concern about the surrounding rear windows that was off-key. 7. He slept in the living room, didn't go near the bedroom, during the night before the departure of the trunk.
The truth slowly begins to dawn on the protagonist and the reader (who can barely set the story aside as the plot unfolds).
Woolrich is a master of suspense -- just like Hitchcock. Too bad his name isn't as well known these days.
