"Hello!" Robinson said, "I suppose that isn't an unfair advantage, Mr.
Blackburn. Still, I'd rather she hadn't been told."
"He's told me nothing," Katherine answered. "I came back to the corridor;
I heard everything you said."
"Maybe it's as well," Robinson reflected. "It certainly is if what you heard has shown you the wisdom of giving up the whole thing."
She stared at him without replying.
"Come now," he wheedled. "You might tell us at least why you stole and secreted the evidence."
"I'll answer nothing."
"That's wiser, Katherine," Graham put in.
She turned on him with a complete and unexpected fury. The colour rushed back to her face. Her eyes blazed. Bobby had never guessed her capable of such anger. His wonder grew that her outburst should be directed against Graham.
"Keep quiet!" she cried hysterically. "Don't speak to me again. I hate you! Do you understand?"
Graham drew back.
