Two famous businessmen die one after another in San Francisco. In both cases, the killer's handwriting is the same: the victims were sedated with sleeping pills and strangled with their bare hands. Both have an inscription on their hands in Latin: “Being late is unacceptable.” A detective from Russia, Oleg Potemkin, who joined the investigation, establishes that the victims loved painting and at different times ordered their portraits from the same artist. Isn’t this where the solution to the crime lies? Or is it all about the Latin inscription, which turned out to be the motto of an elite military unit that fought in Iraq? Its veterans have a special view of art and... very strong hands.
