'Steve telephoned me you were too ill to go to the dance,' explained Charlie, 'so I thought I'd come and make inquiries. I quite expected to find you in bed with a nurse and a doctor or two at least. What is it?' He smiled.

'Nothing,' she replied. 'Only a headache. It's gone now.'

She stood against the mantelpiece, so that he should not see the white parcel.

'That's good,' said Charlie.

There was a pause.

'Strange, Li Hung Chang dying last night, just after we had been talking about killing mandarins,' she said. She could not keep off the subject. It attracted her like a snake, and she approached it in spite of the fact that she fervently wished not to approach it.

'Yes,' said Charlie. 'But Li wasn't a mandarin, you know. And he didn't die after we had been talking about mandarins. He died before.'

'Oh! I thought it said in the paper he died at two o'clock this morning.'

'Two a.m. in Pekin,' Charlie answered. 'You must remember that Pekin time is many hours earlier than our time. It lies so far eastward.'

'Oh!' she said again.
