'But how do you know that Chin Choo still possesses the idol with the secret drawer?' Mr. Page inquired, when Ping Wang finished speaking. 'He may have sold it?'

'That is not at all likely,' Ping Wang declared. 'I know that he has had it fixed up in his chief room, and there it will remain as long as the house stands, or until Chin Choo moves somewhere else.'

'And you think that Chin Choo cannot discover that the idol contains precious stones?'

'I am certain of it. My father was a richer man than Chin Choo imagined, and the wealth that the murderer found in our house was more than he had expected. He is quite certain that he has found all my father's wealth. If he were not, he would never think of looking for it in the image.'

'But do you think it possible to get into Chin Choo's house and remove the idol without being discovered?'

'I am certain of it; of course, I shall watch for a favourable opportunity.'

'Well,' Mr. Page said, after a few moments' thought, 'I must think over the matter for a few days before deciding whether I can permit Charlie to accompany you.'

'I wish I could go with them,' Fred joined in. 'I don't desire a share of the treasure. I simply want to go for the experience.'

'But how about your studies?' Mr. Page asked.

'I wouldn't neglect them. I would read hard on board, and as my next examination does not come on for nearly two years, I shall have plenty of time. And when I'm in China I shall be able to study tropical diseases. Medical men are very keen on that, nowadays.'
