Vladimir Arkhipov quietly lived in a luxurious "bachelor flat" with a faithful mastiff and was not going to change anything in his life. It was all against his will.... Died stranger-neighbor Lizaveta and left him an apartment and his adopted “orphan girl”. Orphan in fact turned out to be an adult girl Masha, who shocked the imagination of a lonely Arkhipov .. But why did the neighbor not leave the apartment to her? Isn't it because people from the Path to Joy sect claimed it, who began besieging Masha immediately after Lizaveta's death . Then a half-brother from the province fell around Masha's neck, and then they both disappeared. Worried about their disappearance and thoughts of a strange death of a neighbor, Arkhipov visits a “bad apartment” and finds the corpse of a sect lawyer there. How did he get here? Who killed him? Really... Masha?
