‘I’ll take a peep through the window,’ said Mortimer.

‘No, don’t!’ Eugene caught him by the arm. ‘Best, not make a show of her. Come to our honest friend.’

‘His daughter has been out, thinking she heard him calling, unless it was a sign to him to keep out of the way. It might have been.’

‘It might have been Rule Britannia,’ muttered Eugene, ‘but it wasn’t. Mortimer!’
