Lev is in his study looking for a confidential file.
You are not, in general, supposed to lose confidential documents. But the floor of Lev's study is covered with layers of books he bought, books he accidentally stole from the library, papers, files, dissertations, forms signed and unsigned, pens, batteries, broken laptops, and similar detritus. If an archaeologist wished to do an excavation, he could come up with a pretty good reconstruction of Lev's career from his floor.
And so there is a file that contains the personal information of the last dozen traitors the Eyes caught in a sting off Closet; it was supposed to be on Lev's desk, with the other things he is working on; it is not on Lev's desk; he has no idea where it is. He is pretty sure it is somewhere on his floor and was not walked off with by a Canadian spy or a member of one of the dozens of half-hearted resistance groups. He is not sure at all, however, that the Eyes will agree, and he does not at all want to be subject to his own work.
You are commanded to pray without ceasing. For once in his life, Lev is following a commandment. He is praying without ceasing that he finds this file.
He thinks darn, considers the situation, and then escalates to damn.
