Mrs. Mallett, a close observer of what was going on, started as her parlour-maid's name was called, and lifting her eye-glass surveyed the girl with a wondering stare of prolonged inspection. And in the dock Krevin Crood also let a start of astonishment escape him; he, too, stared at Louisa Speck, and a frown showed itself between his eyebrows, as if he were endeavouring to explain her presence to himself.

Tansley, too, noticed these things, and bent towards his companion with a meaning glance.
