Oh, these Lola and Marquis! Before they have time to get out of one scrape, they immediately find themselves in the next. This time, the extravagant old woman Anna Arkadyevna turned to Lena Marquis for help. She is convinced that they are trying to rob her apartment. And the attackers are hunting not just anyone, but her favorite pug Dan. It seems to the marquis that the lady is not all right in her head (after all, eighty years is not a joke). This means that the business is a piece of cake and not worth a damn for a top-class specialist. However, a seemingly small matter turns out to be a real test for Leni. And, having involved Lola, his faithful fighting friend, in the investigation, he intends to go to the end, because his professional reputation is at stake.
