Agent 013

Tatyana Sergeeva is alone again: her beloved husband Gri left for a new assignment, and from him there’s been no word or rumor for ages… Only work can help Tanechka distract herself from jealous thoughts. This time she went home to her grandmother’s lodger—an extravagant old woman named Tamara Kuklina, who, as it is said, is being slowly killed by mysterious sounds.
But when Tanyusha felt sick and, with her own eyes, saw mice pouring out of the apartment in a crowd, she realized: the client isn’t crazy at all! Behind the baseboard there was a small black box—the source of ultrasonic vibrations. So who planted it in the innocent old lady? The trail led Tanyusha to… a dump, where more than one generation of “trash collectors” work, profitably selling the treasures they find. But no one there needs Madame Kuklina for free! Or are they trying to trick Tanyusha cleverly?
