‘Yes, very. Why?’

‘Well, were you talking to yourself? Helen and I both woke in the night, and heard talking in your room. I had had some dream that frightened me, and I nearly came downstairs for human companionship.’

‘Why didn’t you?’

‘I was too sleepy. But—were you talking?’

‘No. You were dreaming. So was Helen. I may have groaned now and then over proofs, but not more than that.’

Legs nodded at Helen.

‘I told you it was ghosts,’ he said.

‘And you heard voices too?’ I asked Helen.
