Murder Mystery: Who Did It?

Start with the lead-in questions about why people enjoy murder mysteries and what makes a good detective. These warm up the kind of thinking students will need throughout the lesson. Most B2 learners have watched at least one crime show, so they usually have plenty to say here. After a few minutes of discussion, move to the vocabulary slide. Eight words is manageable, and some like “suspect” and “detective” will already be familiar. Spend more time on “red herring” and “alibi” since these come up in the clues later. Ask students to use each word in a sentence so you know they have got it before the mystery starts.

Introduce the case next. Amanda Black, a famous author, has been found dead in her study. Five people were in the house. Read through each suspect’s description together and give students a minute to take notes on anything that stands out. The timeline slide follows, and this is where groups start spotting gaps and oddities. Do not rush this part. Let them compare ideas and form early theories before the first clue drops.

Present the eight clues one at a time. This is the core of the lesson and where the energy builds. After each clue, give groups a minute or two to discuss how it changes their thinking. Some clues point toward Tom, others toward Mark or Dr. Claire. Remind students that not every clue tells the truth, and some are designed to mislead. By clue five or six, most groups will have a strong suspect in mind, but the later clues often shake things up. Encourage students to challenge each other and explain their reasoning using the target vocabulary. Phrases like “she had a motive because…” and “that could be a red herring” should come up naturally.

After all eight clues, students make their final accusation and explain why. Then reveal the answer: Rachel did it. She poisoned the wine, argued with Amanda when the plan failed, and used the trophy instead. She planted the gardener’s boot prints as a red herring but left her own fingerprint on the weapon. The follow-up questions ask whether students guessed correctly, which clues misled them, and whether the crime was planned or spontaneous. End with the Agatha Christie quote and introduce the homework. Students pick one of three mystery prompts and write their own short story with suspects, a timeline, and clues. They present it next class, and their classmates try to solve it.
