Hermanos y Detectives is a series from Spain, an adaptation of the Argentinian series by the same name. It tells the story of Daniel Montero who works in the police force. After the death of his father he finds out he has a half sibling, Lorenzo. The boy is only eleven years old and has no other alive relatives, so a judge determines he must live with Franco. But Lorenzo is a very particular boy: he has a very high IQ rate, so in a way, he is like a little Sherlock Holmes and will help Franco solve very complicated murder cases. The TV show is done in a retro style, very much like the old series that people used to watch in the 60's and 70's, with some reminiscence of series like "Starsky & Hutch".
