"Fair," said Koko; "yes, a fair price."
Miss Cook ended up with a loud and inharmonious chord, and rose from the piano.
"Come, Dora--we must be going."
"Oh, don't go yet," urged Koko.
"We must--it is getting late, and Dora is expected at home. Good-bye, Mr Somers."
They shook hands, and Miss Cook sauntered out into the passage.
And now Dora had to say good-bye.
"Mr Somers--I know why you sold those books. You wanted to help Dr Mortimer."
Koko gazed at her for a few moments without speaking, and then said, quite simply: "Yes, I did. Jim's my best friend. I'd do anything to help him."
