"Ah," said Olivia significantly, "so she did work for that. Go on."

The letter went on as follows:--"I didn't like Miss Pewsey who was old and ugly and evil--much worse than I ever was, in my worst days. But she haunted my house and I got used to her. I used to smoke opium, and grew very ill. In fact on more than one occasion I became delirious. Miss Pewsey came and nursed me. She took advantage of my delirium to learn the whole story of the fan, and learned also--don't be startled at this Mrs. Ainsleigh--that through me Markham had lost his life."

"We know that from the Marquis," said Rodgers, "but I suspect Mr. Forge wouldn't have spoken out had he not guessed the Marquis would tell the whole yarn. Go on Mr. Ainsleigh."

"Miss Pewsey," went on the letter, "insisted that I should marry her, or else she threatened to reveal the story to Rupert. I was unwilling that this should be, as I thought--and very rightly--that I should get into trouble."

"And he would have," Rupert, broke off grimly to explain, "I should have shaken the life out of him. However, to continue," and he again began to read this highly interesting letter. "I therefore agreed to marry her, but always sought an opportunity of escape. During one of my insensible fits after a bout of opium smoking. Miss Pewsey took the key from my watch chain and opening the cabinet gained possession of the fan. I denied this to Major Tidman at Miss Pewsey's behest, or else Miss Pewsey would have denounced me."

"Not she," said Rodgers, chuckling, "she would have lost her husband had she done so."

"She has lost him in any case," said Olivia, "but I can tell you what is in the rest of the letter, as I see Rupert is tired of reading. Miss Pewsey gave the fan to Clarence to give to me----"

"To win your favour," said Rupert.

"No. To bring about my death. Miss Pewsey thought if I was out of the way, she would get Aunt Sophia to leave her the money."

"What a wicked woman," said Lo-Keong, "we have none such in China."
