In the twenty-second century, humanity achieved tremendous technical progress and managed to build a large-scale system of colonies, solving the problems of transspace communications and fuel production. Such unprecedented results were achieved thanks to the long-term work of the North family, consisting of numerous clones. The Norths own enormous wealth and hold key positions, and when one of the clones is found dead in Newcastle, a real scandal breaks out. In addition to the motive, the method of murder also seems mysterious - with the help of a certain five-bladed weapon, the victim’s heart was ripped out. The circumstances of the death are strikingly similar to another case that occurred several years ago on the planet St. Libra, when another North died as a result of a massacre. Angela Tramelo was accused of the crime, but the woman, sentenced to life imprisonment, swore her innocence and claimed that the house was attacked by an alien monster. No one believed her then, but after the murder in Newcastle this version no longer seems so implausible, since the same handwriting is clearly visible in the cases.
