The first game book based on chess
Ever since she made a serious mistake in an investigation, Inspector Beatriz Moreno only deals with minor cases. That is why she is surprised when her superior puts her in charge of a strange and disturbing case that has just appeared at the police station: someone who calls himself Chess Master has sent a letter stating that in seven days he will commit a murder and that, for clues about the identity of the victim, it will be necessary to solve chess challenges.
It may be nothing more than a bad joke, but Bea can't fail again. To unravel the mystery, she must first learn all the secrets hidden in this world of sixty-four squares.
A very original book in which the movement of pieces on the board serves to advance the story.
