The Gingerbread House Architect

Is there life on Mars, or is there no life on Mars - science does not know. But the planet Celta is another matter. Valentina Steklova, who rushed into Ivan Podushkin's office, claimed that she was born on this exotic... planet.
Ivan was not ready to meet a representative of an extraterrestrial civilization, but he still listened carefully and even tried to understand the rambling remarks of the visitor. But here was the irony! Valentina suddenly lay down on the office couch, closed her eyes and… teleported, that is – ugh! - died.
Ivan had to look for the answer to the question: what did Valentina die from. Soon, one curious detail became clear. It turned out that Steklova was a tough businesswoman, the owner of an entire entertainment town where not quite ordinary people lived. They all pretended to be descendants of aliens… And then Nicoletta and Irene found him a robot bride and are filming a show right in his home. What if he has a stroke too!
