"And so she is," said the Major angrily, "she promised to marry me if I went to China and learned how your father came by his death. I did go, but I came back without learning more, than that he was murdered, so Miss Wharf refused to keep her promise. I believe it was that Pewsey cat's fault."

"Well--well--go on," said Rodgers looking at his watch, "all this business is very round-about. I want to get on with my work."

"This may have to do with it," said the Major smartly. "Well, I was in Canton, and intended to go up to the Kan-su province to make enquiries. I met Forge in Canton. He had just come from Pekin, and showed me round. He laughed at the idea that Markham had died by violence, and said it was dysentery."

"So he always said," murmured Rupert, who listened intently.

"And told a lie," retorted Tidman, "however I believed him, but all the same I intended to make enquiries at the mine of the Hwei River in the Kan-su province. But I stopped in Canton with Forge for a time, as he said he would go up with me. In some way, the fact of my trying to learn the truth about Markam's death got about."

"No doubt Forge told it to others," suggested Rupert.

"I don't know. I never got to the bottom of the business. But one day a half-starved Chinaman stopped me in the street, and told me he could explain, if I came with him. I went to a miserable house in a low part of the city. The man closed the door, and then drew a fan from his breast--"

"The fan in question?" asked Rodgers making a note.

"Yes--the very article. He told me that this fan would reveal the truth, and offered it to me."

"For money?"
