I, Evlampia Romanova, unexpectedly became... a mother to two charming little children at once! Oh, what trouble I had before I found them a "Mary Poppins"! She’s a bit eccentric, of course, but there’s no time to look for another nanny—a new investigation is on the agenda! My neighbor Valya Vesnina suspected that her mother had died not from measles at all. As it turned out, the childhood illness really had nothing to do with it, and the Vesnin family are simply world champions in lying! Outwardly everything is proper and respectable, but in reality the neighbor’s parents were cheating on each other competitively. Valya’s younger sister Larisa is no better—she looks like an innocent little forget-me-not, but two years ago she got into a dubious mess and nearly died... And now someone is calling Larisa on her cell phone and saying: "You killed your mother!"
