R. Austin Freeman, The Mystery of Angelina Frood… (1925)
“ What we have to settle beyond the shadow of a doubt is the question, 'What has become of Angelina Frood? Is she dead? And, if she is, what was the cause and what were the circumstances of her death?' The evidence in our possession points to the conclusion that she is dead, and that she met her death by foul means. That is the belief that the known facts produce. But we have got to turn that belief into certainty. Then it will be time to inquire as to the identity of the criminal. ”
