Book 7
2.8
The act itself again sometimes involves a single question, as, for example, whether a man is dead, and sometimes two, as, for instance, whether he died of poison or of some internal disease. Another form of conjecture is concerned with the act alone, it being admitted that if the act was really committed, there can be no doubt as to its author. A third form is concerned solely with the author, the act being admitted and the dispute turning on the question as to who committed it. This third form is complex.
2.9
For the accused either confines himself to denying that he did it or accuses another of having done it. Further, there is more than one way of transferring the charge to another. At times this results in mutual accusation, which the Greeks call ἀντικατηγορία, and some of our own authors concertative accusation. i.e. mutual or reciprocal accusation, see VII. i. 3. At times, on the other hand, the charge is transferred to some person who cannot be brought to trial, and may be either known or unknown: again, if the person is known, he may be someone outside the case or the victim himself, who may be alleged to have committed suicide.
2.10
In such cases we compare characters, motives and other circumstances in the same way as in eases of mutual accusation. Cicero, for instance, in the pro Vareno diverts the charge from the accused to the slaves of Ancharius and in the pro Scauro throws the suspicion of Bostar's murder upon his mother.
