How does separate examination expose the accusation against Susanna?

The edition explains that Susanna's history stood at the beginning of Daniel in old Greek and Latin copies until Jerome moved it, because it is absent from the Hebrew; it also records its Catholic canonical reception. In Babylon, the rich and highly honored Joakim marries Susanna, Helcias's beautiful, God-fearing daughter, whom her just parents taught Moses's law. Two elders appointed judges that year hear cases at Joakim's house. Watching Susanna walk at noon, both develop lust, turn their minds from heaven and forget just judgments. Initially ashamed to disclose it, they separately leave for dinner, return, discover each other's desire and agree to find her alone.

In hot weather Susanna goes to wash in the orchard with two maids. She sends for oil and washing balls and has the doors shut. The hidden elders run to her and demand intercourse, threatening to accuse her of sending away the maids to be with a young man. She sighs at the threatened death but chooses falling into their hands without the act rather than sinning before the Lord. She cries out; they also cry, and one opens the door. Servants arrive by the back door, ashamed at an accusation never previously made against her.

Next day the elders summon Susanna with parents, children and relatives. They order her face uncovered to satisfy their lust; her friends weep as the elders put hands on her head. Trusting God, she looks toward heaven. Their false testimony claims a young man lay with her and escaped through the door because he was stronger, while Susanna refused his name. The assembly believes them as elders and judges and condemns her. She appeals to the God who knows hidden and future things, saying they have witnessed falsely. The Lord hears. As she is led to execution, he raises the holy spirit of young Daniel, who declares himself clear of her blood and asks why they condemned without examination. The people return to judgment.

Daniel separates the witnesses. Rebuking the first for oppressing innocents and releasing the guilty, he asks which tree sheltered the alleged act; the answer is a mastic tree. Daniel announces that God's angel will cut him in two. He rebukes the second as of Chanaan rather than Juda, saying lust deceived him and other women submitted through fear whereas this daughter of Juda refused. The second names a holm tree; Daniel announces the angel's sword. The assembly blesses God, rises against the elders convicted by their own mouths and puts them to death under Moses's law, saving innocent blood. Helcias and his wife, Joakim and the relatives praise God because no dishonesty was found in Susanna; Daniel becomes great before the people. The chapter ends with Astyages's death and Cyrus receiving his kingdom. It does not specify stoning as Susanna's proposed execution method.
