Describe the character of the professor in "Saboteur." Give at least three details from the story to support your description.

The professor in "Saboteur" is portrayed as a cunning and manipulative individual. Three details from the story that support this characterization are:

1. The professor uses his position of authority to falsely accuse the protagonist, Mr. Chiu, of being a saboteur, despite there being no evidence to support such a claim. This shows that the professor is willing to abuse his power in order to achieve his own agenda.

2. The professor is shown to be calculating and deceptive in his interactions with Mr. Chiu. For example, he pretends to sympathize with Mr. Chiu's illness and offers him tea, only to later reveal that the tea was poisoned. This demonstrates the professor's willingness to resort to underhanded tactics to achieve his goals.

3. The professor's lack of remorse or empathy for the harm he causes is also indicative of his character. Despite Mr. Chiu's suffering, the professor shows no regret for his actions and instead coldly dismisses Mr. Chiu's protests. This highlights the professor's callous and unscrupulous nature.
