1x4 - If It's Tuesday... It's Murder

FRIDAY. Our four investigators uncover new clues all pointing to a suspect: Nicolau. Pura and Alicia follow him closely. Daniel, the cleverest of the group, continues investigating the treasure. He deciphers that the Cross of Portugal is a key element, but incredibly, Nicolau gets ahead of him. Another crime, the police once again at the Hotel Marqués, and all the tourists become suspects again.
