"Then why was she so distressed in the beginning?"
"Well, there was something that would have looked like evidence to a man," said Sadie scornfully. "So naturally she didn't want to tell you."
"Did she tell you?" I asked, a little huffed at the thought that Sadie was getting deeper in the confidence of my client than I.
"Yes, to-day. She didn't tell me about her feelings, of course. I guessed that part."
"What is this mysterious thing?"
"She only told me because since she saw the cryptogram she knows there couldn't be anything in it."
This was getting denser instead of more clear. "What was there about the cryptogram that eased her mind?" I asked.
"She knows that it couldn't have been written to Roland Quarles because he has no idea of leaving the company."
"Oh, hasn't he!" I thought to myself. How strangely loving women reason. Aloud I said: "Now for the thing that a mere man would have considered evidence."
"Don't try to be sarcastic," said Sadie. "It doesn't suit you."
