Four Detectives

New adventures of the detectives from the Five Houses! The cases are becoming increasingly convoluted, the criminals more skilled, and the investigations more dangerous. But this does not scare the quartet of detectives: Mitya Filin and his loyal friends — Anya Volkova, Seryozha Ivantsov, and Lena Filippova. They continue to take on the most challenging cases and devise crazy theories in their headquarters over cups of coffee. Together they will catch the criminal who stole the paintings of a famous artist; find Anya's doppelgänger and almost end up in the movies; organize surveillance on a very suspicious classmate and even get on the trail of AI! «My old principle of investigation is to exclude all impossible assumptions. Then the remaining possibilities, no matter how improbable, must be the truth,» — Sir Arthur Conan Doyle, Sherlock Holmes, and Mitya Filin.
