I don't say that she came to do it.

But she saw that knife lying handy on the library table and she did it," said Hutchings with the same vehemence.
"Any one who passed through the library would see that knife," said Mr.
Flexen carelessly, but his eyes were very keen on Hutchings' face.
Hutchings was pale, and he went paler.

He tried to stammer something, but his voice died in his throat.
"Well, I'm sorry you can't give me any information about this lady.
Good afternoon," said Mr.Flexen, and he turned on his heel and went back to the car.
He was impressed by Hutchings' air and manner.

Of course, believing himself to be suspected, the man was under a strain.
