Transcript
[Extract from a popular penny novel]

They met in secret and spoke in whispers, their huddled forms cloaked against the night, their heads bowed low, so as to almost touch.

''But then there was betrayal, as terrible and as cold as the snows of Tyvia. Each man had a a dagger—the blades long and silver and hidden no longer! Together, the instruments of death were raised. Together they fell, as did the men, their bodies sliding to the earth in a silence that was befitting their craft. The men would not move again, their secrets safe to the very grave!''
