Unable to unequivocally prove John Cavendish’s innocence, Heavywether casts doubt on Lawrence to illustrate just how much evidence there is against
other people involved in the case. Lawrence, for his part, is in a particularly tricky position, since the evidence against him seems just as definitive and condemning as the evidence against John. In fact, the evidence against both brothers is so convincing that some readers might suspect that they worked
together to kill Emily Inglethorp.
