A prompt asking students to argue which character deserves the most suspicion is a natural fit for a detective novel. In La Voix sur la montagne, the investigation touches the household staff, a set of estranged relatives, and an authoritarian son who resents the detective's presence. Students have many possible suspects to consider, which makes this an excellent exercise in building an argument from evidence.

The crucial grading decision is to evaluate the quality of the reasoning rather than whether the student guessed correctly. Even a student who names a character the author did not intend can write a strong essay if the evidence is well chosen and the logic is sound. This approach keeps the focus on skills students can transfer to other texts.

Teachers should also be careful about spoilers within the class. Some students will finish the book before others, and the essay should be assigned at a point where the answer is not yet fixed for everyone. Timing the prompt to a mid-novel stage allows students to argue from the information available at that point.

What a strong argument looks like

A strong essay explains why one suspect is more suspicious than the others and addresses the best case for the alternatives. This counterargument step is what separates a thoughtful essay from a one-sided one. Students who consider why another character might be innocent demonstrate analytical maturity.

• Names a specific suspect and states the reason in a clear thesis.
• Uses at least three distinct pieces of evidence from the text.
• Distinguishes between facts in the story and the student's own inferences.
• Addresses at least one counterargument or competing suspect.
• Acknowledges uncertainty where the text does not provide proof.

Dealing with weak inference

A common problem is a leap from a small detail to a large conclusion. A student might argue that a character is guilty simply because they were unfriendly to the detective. Feedback should ask whether other explanations could account for the same behavior and invite the student to strengthen the link.

It can help to introduce a simple distinction between evidence, inference, and speculation. Evidence is what the text states, inference is a reasonable conclusion drawn from it, and speculation goes beyond what the text supports. Asking students to label their own sentences in this way sharpens their thinking and makes the essay easier to mark.

Marking and moderation tips

Because the essays will reach different conclusions, a teacher may be tempted to judge them by personal agreement. A rubric focused on evidence, reasoning, and organization avoids this pitfall. It also provides a basis for explaining grades to students who feel their suspect was equally plausible.

Tools like GraideMind can help maintain consistency by applying the rubric to each essay in the same way, regardless of the suspect chosen. The teacher then reviews the output to ensure that the reasoning has been evaluated fairly. This is especially useful when essays vary widely in their conclusions.

Extending the exercise

After the essays are submitted, a class debate lets students defend their choices orally. Hearing a peer's counterargument often leads students to refine their own thinking. Teachers can then invite a short written reflection on whether the debate changed anyone's mind.

Revisiting the exercise after finishing the novel is another valuable step. Students can reflect on how their original reasoning held up and what clues they might have missed. This look back builds metacognitive awareness and reinforces the value of careful reading.
