  1. This is a difficult one!, the more I try to solve it the more difficult it seems, but i'll say that Alice's husband was the victim and Alice's daughter was the criminal...
    Am I right?

  3. Solution: If you consider that Alice's son and daughter were adults, the only possible scenario is...Alice was with her son at the bar. Then the child who was alone was her daughter. Therefore Alice's husband was with Alice's brother on the beach. The victim could not be Alice's husband because none of the others could be his twins. But the victim could be Alice's brother because Alice could be his twin. Finally, Alice's brother was the victin and Alice's husband was the killer.
