A famous scientist was found murdered in her lab in the chemistry department! Before she died, she was able to smeer a few numbers with her blood on the wall:
Scotland yard believes this might be a clue to find her murderer(s)! Strong suspects are some of her colleagues who were unable to provide an alibi and were reported to have had not the best of relationships with her in the past: Edward, Gabi, Carl, Sahra, Felice und Antonio.
Can you figure out who these numbers might refer to?
The answer to last month’s riddle: It’s a dice. An explanation: “It’s always 1 to 6”: the numbers on the faces of the dice, “it’s always 15 to 20”: the sum of the exposed faces when the dice comes to rest after being thrown, “it’s always 5”: the number of exposed faces when the dice is at rest, “but it’s never 21”: the sum of the exposed faces is never 21 when the dice is at rest, “unless it’s flying”: the sum of all exposed faces when the dice is flying is 21 (1 + 2 + 3 + 4 + 5 + 6).
