Смех и грех Ивана-царевича

It's true what they say: habit is second nature! For a long time Ivan Podushkin has not served as a secretary for the business lady Eleonora, but he ran to her at the first call! Of course, Nora again needed his services as a private detective - Lyudmila Vinivitinova-Belskaya turned to her and asked her to investigate the death of her father. Officially, he died of a heart attack, but some facts made the eldest daughter suspect that his second family had a hand in the death of the pope. So Ivan Pavlovich had to try on the role of a butler in a princely house! In fact, the Vinivitinov-Belskys are not princes at all, this legend was invented by Lyudmila's great-grandfather, and since then the cunning family has skillfully used it. But why did Ivan suddenly see with his own eyes the ghost of a killer dog, which Luda's father invented to attract tourists to the mansion?
