'Hark!' she would say every now and then; or, 'Listen! What was that?'

'Only the cry of a burrowing owl,' Moncrieff might have to answer; or, 'Only the yap of a prowling fox.' Oh, the waiting, the weary waiting!

'Egyptian darkness!' murmured the old lady in her sleep. Then in louder, wilder key, 'Smite them!' she exclaimed. 'Smite this host of the Philistines from Gideon to Gaza.'

'Dear old mither, she's dreaming,' said Moncrieff. 'But, oh, we'll laugh at all this by to-morrow night, Aileen, my darling.'
