'No; off his head. Send a couple of your men in here. I think I'll get my hands on that gold presently.'

The sergeant withdrew, and Downy touched Chris on the shoulder.

'It's a bad business, miss,' he said. 'You made a plucky fight, but this was inevitable. Will you tell me where he was hidden?'

Chris arose and stood with her back to the wall and answered him in a firm voice. She understood the futility of further evasion.

'He hid in the tank,' she said. 'It has a false bottom, and you get in from below.'

The detective expressed incredulity in a long breath.

'Well, that fairly beats me,' he said. 'When did he fix the tank?'

'I do not know. I had no idea it was done until the night of the arrest of Rogers.'

At this moment Casey and Keel entered.

'Stand by the man, Casey,' said the detective. 'Keel, follow me.'
