The others looked relieved; for they knew, now, that they would not have to break this news to Eliza. "So you are aware that when accounts are settled in Lyon, it is all done on the books. A man seated at a banca will write in his book, ‘Signore Capponi owes me 10,000 ecus au soleil ’—a currency that is used only in Lyon, by the way—and this, to him, is as good as having bullion in his lock-box. Then when the next fair comes around, perhaps he finds himself needing to transfer 15,000 ecus to Signore Capponi, and so he will strike that entry from his ledger, and Signore Capponi will write that he is owed 5,000 ecus by this chap, and so on."
