“What about the butler—Stimson?” asked Landis.
“Don’t think I—yes, I did notice him trying to quiet Susan. He was a bit white but otherwise quite his capable, dignified self.”
“Did you notice anything that struck you as peculiar? Take plenty of time to think, please.”
The long library was silent for a few minutes except for the rustle of the fire.
“Afraid I didn’t,” admitted Graham at last.
“Were any of these library windows open from the bottom when you first came in here?”
“No. I’m sure they weren’t. I looked.”
“Aren’t the shades usually lowered by this time of night?” inquired Bernard.
“Yes. Stimson lowers them and closes the windows while we are at dinner. But tonight the sergeant chased him out and told him not to touch anything. He went in while I was at dinner and came back and told me with some stiffness!”
Landis smiled.
