The Mysterious Whisper

Three friends — Ilya, Kira, and Sashka — unite as team «IKS» to investigate mysterious events. They study, befriend, quarrel, and make up… and additionally — they take on cases that send shivers down the spines of even the teachers!
 
Once... again, there is unrest in the old boarding house. During breaks, students whisper about strange sounds coming through the school speakers. Some hear their names. Others — strange words. Still others — an ominous whisper: «Soon you will all be in trouble!» And only the «IKS» team realizes: this is not just a system glitch. It is someone's cunning game.
 
The stories take place in a unique setting — a school-boarding house located in a former merchant estate from the nineteenth century. The author of the series, Svetlana Krivoshlyakova, masterfully describes the mysterious atmosphere of the old building and the secrets it holds. The connection between the spirit of the closed boarding house and the modern life of ordinary schoolchildren makes the reading captivating, while the unraveling of the mysteries leaves a lasting impression.
