Letter from Zhiznomir to Mikula: You have bought a female slave in Pskov. And now the princess has arrested me for it. (Obviously she has recognized the slave as having been stolen from her, and Zhiznomir is somehow connected with the affair, maybe as Mikula's family member or business partner.) But now druzhina has guaranteed for me. And now send a letter to that man (whom you have bought the slave from) and ask him whether he has another female slave. (This other slave would have to be given to the princess for the time the stolen slave would be needed as "corpus delicti" in a lawsuit to find out who the thief was.) And I want to buy a horse and have the magistrate (the "prince's man") sit on it and initiate a "svod" (the legal procedure to trace a whole buying chain back to the original seller and ultimately the thief). And if you have not taken the money, do not take anything from him (i.e. the slave-trader, because otherwise the whole plan might leak out).
