Riddle 1: Two griffins fall into a large glass bowl. The glass bowl's sides are slippery and there is a liquid in the bottom. The liquid dampened the griffins' wings. One griffin did something while the other did not. The giffin that did something survived while the other drowned in the liquid.

Riddle 2: At the scene of the murder of Gideon's sister, five suspects, one of whom is the guilty party, are being interrogated by James. Each of the suspects gives one statement. Two suspects are lying. The statements are listed below.
Rosalie: Caspian committed the murder
Cosmos: I did not do it
Joanne: It was not Anahita
Caspian: Rosalie is lying when she says I did it
Anahita: Cosmos is telling the truth

Riddle 1: To solve this riddle, we need to analyze the given information carefully. Two griffins fell into a large glass bowl with slippery sides. There's also a liquid in the bottom that dampened their wings. It is mentioned that one griffin did something while the other did not. The griffin that did something survived while the other one drowned in the liquid.

Based on the information provided, it can be inferred that the griffins' wings were dampened, making them unable to fly. Since the sides of the bowl are slippery, the griffins would not be able to climb out. Therefore, the griffin that did not do anything simply couldn't escape and drowned in the liquid.

The griffin that did something, on the other hand, took an action that allowed it to survive. One possible action could be to shake or flap its wings vigorously, trying to dry them and regain their ability to fly. By doing so, it would be able to stay afloat and avoid drowning in the liquid.

So, the answer to the riddle is that the griffin that survived found a way to dry its wings, while the other one did not.

Riddle 2: To solve this riddle, we need to analyze the statements given by the suspects and identify any contradictions that can help us determine the guilty party.

Let's examine the statements:

1. Rosalie: Caspian committed the murder.
2. Cosmos: I did not do it.
3. Joanne: It was not Anahita.
4. Caspian: Rosalie is lying when she says I did it.
5. Anahita: Cosmos is telling the truth.

From the given information, we know that two out of the five suspects are lying.

If Rosalie's statement (1) is true, then Caspian committed the murder. However, Caspian's statement (4) claims that Rosalie is lying. This means that either Rosalie or Caspian is lying.

If Cosmos' statement (2) is true, then he did not commit the murder. Anahita's statement (5) confirms this. However, we also know that two suspects are lying, so at least one of them is lying.

Joanne's statement (3) implies that Anahita is not the guilty party.

Based on the analysis, we can conclude that Caspian's statement contradicts Rosalie's statement, which means one of them is lying. Since Joanne's statement supports Anahita, and we know that Cosmos is telling the truth, it leaves Rosalie as the only remaining suspect who could potentially be lying.

Therefore, the guilty party is Rosalie, as she falsely accused Caspian of the murder.
