"It would be the safest place," replied Rupert dryly, "however, I intend to try the experiment of waving this fan in the smoke."
"You don't know the kind of smoke?"
"I can guess the kind. Olivia do you remember that joss stick which Mrs. Petley found in the Abbey."
"Yes--at the time she saw the ghost."
"Precisely. The ghost left that joss-stick behind on the first occasion, and the fan on the second. Now I shouldn't wonder if the fan had got into the hands of Hwei, and that he was the ghost."
"What makes you think that?"
"Well, Hwei confessed that he was lurking outside the Bristol hotel to get a chance of killing Miss Wharf when she was lured out by Tung-yu. That gentleman however played false. All the same Hwei was here, and perhaps he came up to the Abbey--"
"Why?" asked Olivia looking perplexed.
"Ah, that I can't tell you. But I fancy the answer is to be found in this fan, as soon as we see the picture."
"But the smoke."
