He looked like a man with some burden on his mind which he was afraid to reveal and unable to throw off.
"Somebody must be found, David, who does understand the case," he said, looking at the helpless figure on the bed.
"Who can we find ?" I asked.
He bade me good-night without answering.

It is no exaggeration to say that I passed my night at the bedside in a miserable state of indecision and suspense.

The doctor's experiment had failed to prove absolutely that the doctor's doubts were without foundation.

In this state of things, was it my bounden duty to tell the medical men what I had seen, when I went back to the house to look for Mr.Keller's opera-glass?
The more I thought of it, the more I recoiled from the idea of throwing a frightful suspicion on Minna's mother which would overshadow an innocent woman for the rest of her life.

What proof had I that she had lied to me about the sketch and the mantlepiece?
And, without proof, how could I, how dare I, open my lips?
I succeeded in deciding firmly enough for the alternative of silence, during the intervals when my attendance on the sick man was not required.
