Lesson preview
Students solve a tense library escape story by reading incident notes, listening to Mara Quinn’s emergency message, and matching clues to hidden objects. They also practice present perfect and modals of obligation while discussing suspicious events, writing a short report, and piecing together the final escape sequence.

The Rainfall Archives are sealed, and the storm is getting louder outside. What clues can you find before the backup battery runs out?
Teacher note: The Rainfall Archives are sealed, and the storm is getting louder outside. What clues can you find before the backup battery runs out?
Teacher note: Vocabulary set for the Rainfall Archives escape-room storyline, covering building features, evidence items, urgency language, and safety actions.
At 21:10, the automatic doors of the Rainfall Archives sealed without warning during a severe storm. Curator Mara Quinn reported a brief flicker in the corridor lights, followed by a loss of control at the main desk. The building’s backup battery is now running, but the emergency system is not responding normally.
A staff note found beside the reception terminal states that the east reading room was checked twice before the shutdown. Another note mentions a missing keycard and a strange sound near the maintenance corridor. No smoke, fire, or structural damage has been reported so far.
For the moment, the safest instruction is to stay inside the archive, avoid unnecessary movement, and collect evidence in order. The next step is to identify what happened just before the doors sealed and decide which detail needs immediate attention.
The Rainfall Archives is a private research library near Edinburgh. In a storm, a backup battery can keep essential systems working for a short time, but it cannot last long. The report below is the first written record of the incident.
Teacher note: Opening incident report that sets up the sealed-library emergency and gives students the first facts to extract.

Create free teacher accountListen to Mara Quinn’s message once, then answer the questions. Focus on what has already happened, what she wants the group to do next, and the warning about the alarm.
Mara: If you can hear this, the automatic doors have sealed and I cannot override them from the main desk. The backup battery is dropping faster than I expected, so we do not have much time. First, go straight to the archive map by the entrance desk. After that, check the torn inventory list near the east shelf. Do not search the whole room at random; the clues are placed in order. One of the answers is hidden inside a coded email on the old terminal. Another digit will come from the items you find beside the map. If the alarm starts again, that means the emergency system has not been reset properly. You must restart the emergency system before the battery fails completely. Move quickly, stay calm, and follow the clues exactly as they appear.
Teacher note: Listening task built around Mara Quinn’s urgent emergency message, with questions focused on sequence, urgency, and the state of the system.

Create free teacher accountWe use the present perfect to talk about events that happened recently and still matter now, especially when the result is important in the present. In the Rainfall Archives, this tense helps us describe what has happened so far and why the situation is urgent.
Use the present perfect when:
If the exact finished time is not important and the result matters now, the present perfect is often the best choice. In this story, it helps us say what has happened up to this point before the next clue appears.
Teacher note: Clear explanation of the present perfect using the archive emergency storyline, with examples and common mistakes for C1 learners.

Create free teacher accountWork with a partner. Student A describes what has happened in the archive so far. Student B asks for clarification, reacts, and gives advice. Then change roles.
Student A
explain one suspicious event you think matters most. Student B: ask one follow-up question and say whether you agree.
Together, decide what the group should do in the next five minutes. Use at least two advice phrases.
Choose one event and explain how it could connect to the sealed doors or the failing system.
Try to keep each turn short and clear. One student should describe, and the other should respond with advice or a question. Use the present perfect when you talk about what has already happened.

Create free teacher accountListen to Mara’s message carefully. Focus on the warning, the place she wants you to check again, and the clue that reveals the next digit of the code.
After listening, answer the questions below in full sentences where possible.
Mara: I found the email. The first line looks harmless, but the hidden text changes everything. The emergency system was not failing by accident. Someone has already entered the maintenance corridor, and that means this is bigger than a simple power problem. Check the map again and look for the shelf marked D-4. That is where the next clue is hidden. The next digit is connected to the number of locked doors on the east side, so count carefully. Do not search the whole archive at random. If we waste time, the backup battery will not last long enough to open the final lock. I have also noticed a second message in the email header, and it suggests the doors were sealed from inside. That makes the situation much more serious than a routine shutdown. Find the shelf, count the doors, and bring the clue to the panel before the alarm circuit fails.
Teacher note: Listening task using Mara Quinn’s decoded email message. Students listen for the cause of the failure, the location to inspect, the shelf reference, and the clue linked to the next code digit.
